Sir, from the wire that u wound over the cardboard, is there only one bare end ?? and later when u connect the LED to the wire !! do u divide the bare end into two !!??
@joysareencool Didn't look at the main project website? This video is not the project, it's just some extras. Follow instructions and drawings on amasci website coilgen.
@joysareencool every piece of wire always has two ends. The electricity inside all wires can only flow if the wire is connected in a circle. The small light bulb is part of the circle.
The electricity was inside the metal wire and inside the light bulb filament. When the magnets move, all this electricity begins flowing at once. It's like a rubber drive belt: the magnets push on one part of this belt, and the entire belt starts to move.
@mohe3439 wires have to be as close as possible to magnets, but a disordered coil works fine.
Better is to wind lots more wire, like 600 or 800 turns. Get cheap wire: mail-order surplus companies sell solenoids, the open-frame kind. Pry apart to get the wire spool. Way cheapr than Radio Shack. Or see lots of wire-spool sellers on the project website.
@Absol2819 You used very thin radio shack enamel-insulated wire? Size #30 gauge? Notice on main project page: don't use different wire, don't use different bulb, don't use different magnets. Use #30 varnished wire from radio shack, or take apart a 24V solenoid to get out the spool of thin wire.
@thehomeslice101 this video is incomplete. It's just an extra on the main website. Need to read the project instructions. Follow the parts list on page 2, don't use substitute parts.
If you use an LED instead of the special Radio Shack bulb, you'll need to add 2X or 3X more wire.
@Absol2819 tried the liste of suggestions in the "debugging" section? Usually the problem is, used wrong parts not on the parts list. Other problem is: didn't spin it fast enough.
@Absol2819 go to the website. Click on "How it works"
Briefly: wires are made of movable electrons and solid, immobile protons. Wires are like pipes full of water. Generators are "electricity pumps." The moving magnet pushes the wire's own electrons along. Electricity is like a rubber drive belt, and a generator is like a drive wheel with the belt of electricity passing over it.
@faight3r nope, that's the misconception. Actually, magnetic field moving and crossing wires will force electricity to start moving.
Wires are like tubes full of marbles, marbles are the electricity. The wires were already full, and the magnetic field just pushes it along. Generators create electron flow, but they don't create electrons.
@wbeaty Thanks. I tried it with the 1.5V 50mA and it worked but i had to spin it ALOT. Luckily mine is a windmill so i don't have to use my hands all the time. Just one more question, how do i connect more wire to the current wire i'm using?
@burnout510 To connect extra wires, if no soldering iron, just totally clean all plastic coating from 1cm ends of wire, and twist together with many twists.
@SejinDivine Efficiency is (bulb watts)/(total watts), where the total watts is coil heating plus bulb heating plus bearing heating. Measure bulb current & bulb volts to get bulb heating. Coil watts is [(open circuit volts)-(bulb volts)]*(bulb current)
@ale5killer exactly right. the bulb flashes each time the magnet flips over (so two flashes per complete revolution.) If you could spin the magnet enough times per second, the filament would remain hot and stay constantly bright between surges of voltage.
@heathertaylorable Yep, big 2" or 3" loudspeaker magnets work fine. But they must flip over, not spin on axis. The coil of wire needs to stay very close to the magnets. It's hard to find the right size of pipe: a pipe that fits close yet still allows the magnets to flip without hitting the inside.
i created a video response. let me know if you got it. i turned the generator into a motor using a 24vdc supply. i also made a commutator so the supply polarity could switch as the magnets spin.
please answer this, it's urgent:$ but as for the efficiency of the generator, we can't find a digital voltmeter at the time, would you know the average amount of energy you put in and the average amount of energy that is produced?
@ZeroGenerations Yep. You'll have to spin the magnets a bit faster. You can even use a red LED if you add lots more wire (like 500 turns.) Or spin it extremely fast with a power drill.
regarding the motor challenge, i would assume that one coil lead would be connected to the battery and the other lead would have to ride on the nail (over the commutator "tape") and a third lead that runs from the nail to the battery?!?! any advice would be great
hey can you recommend another video just like yours that teaches people how to make an improvised object? i find your little project hard but nonetheless i compliment you for making such a cool improvised generator:) pls help me cause i have a project coming up:)

In the article I say: don't use different parts. Don't change parts, use the ones in the list. If you use different parts, the generator won't work, so don't use different parts. I say it about fifteen times!
Hi wbeaty, im basicly making a basic wind turbine and currently working on the generator, is there any spacific way the wire has to be wrapped around on any spacific way the magnets are faccing for example nagative facing in and positive out?
@SkynetNealUK Go check the main article, not just the vid. See above, where it says "Full information at amasci com/coilgen. main project website? The url is also right below the video title.
If instructions aren't followed exactly, it won't work.
The magnets must spin EXTREMELY fast, and a propellor might not work unless you use compressed air to whirl it like a blur. Better is a plastic water propellor and a garden hose with a spray gun. And try 1000 turns of wire, not just 250
@kingniels2 depends how fast you spin it. That special bulb barely lights up at 3/4 volt. The generator won't light a red LED at 1.7V unless you double or triple the number of turns of wire. That, or spin it 2X or 3X faster than human fingers can spin it. Some kids step up the speed: a tiny pully on the nail, a big pulley made from CDs, and a big rubber band as a drive belt. See "DR. GUPTA'S" generators on the links page.
@blood5057 Also the ancient invention called the "fire-drill" can spin these magnets much faster. Fire-drill is a bent piece of wood with a stretched piece of string, the string wrapped around the rod which spins.

@heyitsmecamillexx better if you also put magnets on the wheel rim. That way you form "magnetic gear teeth" to spin the generator fast. See packratworkshop bobble generator
So what would it take to build a magnetic generator on a larger scale? Not to run an entire house, but let's say I wanted to run my gaming PC? I've been trying to do some research but all I can find are these plans people are selling and I don't really feel comfortable trusting them.
@AirSOFTLOVER12 You mean a gasoline generator? Or a wind turbine?
Those plans online are sold by assh***s. The scam goes like this: convince a thousand people to buy fake plans for $70. 80% demand their money back, and the rest don't bother. You've just made fourteen thousand dollars.
Here's what "Free Energy" hobbyists say about those bogus plans: bit.ly / 17S0N4
@theorangem1 you can glue the rectangle magnets side-by-side and repelling. That makes bigger magnets. Stack those up!
A bigger generator can output more wattage. This tiny generator has about 20ohms coil, and 1volt output. So the maximum possible watts is 1/80th W, or 13 milliwatts. But if you could spin it twice as fast as human fingers can, then wattage increases 4X.
So lets say if you had a wind turbine with multiple of these generators, would you be able to increase your amount of voltage? It's probably a stupid question...
@Unequippd All the AC power would have to be synchronized. Make them all on the same long shaft, with magnets permanently attached. Align all the generators together so their AC wave increases at the same time. Then just wire them all in series.
But it's better just to learn to build advanced wind power generators using supermagnets and pancake-shaped coils. Go and find the "otherpower" site with hobbyist wind turbine projects.
mine basically looked exactly the same, sucks though because when I presented it it didn't light as much as i wanted too. Fingers hurt. Wish you can turn it easier.
@FlyCarlos This is the cheap crappy ultra-simplest version. If you improve it, then it gets more complicated and a bit harder to build.
See the main project site, go the the links page for lots of other generator projects on other websites. The DR GUPTA generators give lots higher voltage, but they have handcrank drive belts and stuff.
@wbeaty Yeah, I should of Improved it more. Thanks though I still got an A, and I still remember around 2007 when I watched this video. It was great help and a great video, Thank you.
@FlyCarlos I just attach a drill to the pointed end of the nail and it actually lights up pretty brightly in a dark room. All the kids in my physics class loved this project, thanks wbeaty!
@vicmendoza11 #28 works great. Any larger than that and your coil starts getting too thick. You don't want the outer turns to be too far away from the magnets.
i thought that in order for a copper wire to have current from a magnet it needed and iron core and that the solenoid had to be in the middle of a north and south pole magnetic attraction for it to work
@kobe1bryant1fan The coil just has to enclose a strong, fast-changing magnetic field. In other words, the magnets act like the iron core. The rotating magnets supply the changing N and S poles.
Does spinning a magnet inside a coil create any resistance? not counting the axle friction, if not then if there weren't any air or friction the magnet could spin infinitely?
@Allexxx96Reloaded Yes, read the main project article "FEEL THE ELECTRONS." This resistance is maximum when the coil is shorted, and zero when the circuit is open.
This same resistance can create a magic trick. If you drop a magnet down a copper pipe, it will appear to levitate in the middle of the pipe, and fall very slowly.
So, you're spinning the magnets to make the diode glowing. So... magnets make coil's electrons running from one side to second one, right thru diode. Well you don't have to use your arms, just have to make your magnets running by themselves. They are magnets, allright ^^?
I was wondering if one could use rubber material for the casing? Would rapping the copper around it cancel the magnetic effect inside of it passing threw? Thanks for your time
@Tumlock yep, rubber or plastic or wood is just fine. Don't make it too thick though. The coil of wire must hug the magnet closely. If your box is too thick, then you'll need to add lots more turns of wire.
@shusher0099 more turns of wire gives you higher voltage output. With higher voltage, you won't have to spin the magnets so darned fast. And it's easier to light up a red LED instead of a weird special tiny bulb.
Need help !! On 3:40, how did he connect the magnet to the nail, so when he spins the nail, the magnet spins too.......?? Didn't understand that part........
@SyedRayeed The strong magnets grab the nail with many pounds of force. Slide them around to get them centered. Stuff some bits of cardboard in the gaps on each side of the nail.
@geekatzombies4life Neo magnet strength is about 10X stronger than ceramic. So, if you used four large rectangle neo magnets, then the volts/amps would be 10X higher, and maximum possible power output would be 100X higher. (But this doesn't work if you use a tiny neo magnet!)
@wbeaty when you mean the max power output you mean ........ because i doubt a little ting like this could produce around 3. amps or 70 volts with neodymium
@wbeaty wow this might be my day cause I made one that's portable and I can manage to spin it up to 500,000 rpm. the magnets are almost the size of what you showed in the video except they are neodymium
@wbeaty hmmm thanks :) hey if your rotating a magnet instead of a coil.wat is the formula to find induced emf?? is it the same e = B l v ?
this is a way i found out but don't knw it's correct r not.since emf induced is rate of change in flux, I multiplied the field strength B with the rate of change in area i.e. L x v . So i thought of finding the area of magnet and multiplying it to the number of rotations per sec to get the change in area. am i right in this? if not plz tell the right way
@nigel738 glue some stacks of magnets side by side, so they repel. (Repelling magnets all have N or S on the same end. Attracting stacks are no good, since the poles cancel out.)
Or just use a five pound $100 neodymium hockey-puck magnet ...if you want to DIE!!!
@PACIFICFL0W A generator is like a wheel and drive belt. But the belt is made of electricity. When you crank the wheel, it makes the electricity flow.
If we had a drive belt and two pulleys, couldn't we use some gears to connect the second pulley to the first one? Then it would start cranking itself! It would go faster and faster, then EXPLODE. It's a Mechanicity Bomb. Don't build a drive belt assembly. You could wipe out your neighborhood.
Sir, from the wire that u wound over the cardboard, is there only one bare end ?? and later when u connect the LED to the wire !! do u divide the bare end into two !!??

I'm sure you already know, but I'm betting this would be more ergonomic with a drawstring like a gyroscope or lawnmower.

@LordOfTheGnus Magnets must spin FAST. Or use a bow-drill like ancient firestarter. Or make step-up crank wheels from old CDs and cardboard disks.

So lets say if you had a wind turbine with multiple of these generators, would you be able to increase your amount of voltage? It's probably a stupid question...
Unequippd 3 months ago
@Unequippd All the AC power would have to be synchronized. Make them all on the same long shaft, with magnets permanently attached. Align all the generators together so their AC wave increases at the same time. Then just wire them all in series.
But it's better just to learn to build advanced wind power generators using supermagnets and pancake-shaped coils. Go and find the "otherpower" site with hobbyist wind turbine projects.

mine basically looked exactly the same, sucks though because when I presented it it didn't light as much as i wanted too. Fingers hurt. Wish you can turn it easier.

@FlyCarlos This is the cheap crappy ultra-simplest version. If you improve it, then it gets more complicated and a bit harder to build.
See the main project site, go the the links page for lots of other generator projects on other websites. The DR GUPTA generators give lots higher voltage, but they have handcrank drive belts and stuff.

@wbeaty Yeah, I should of Improved it more. Thanks though I still got an A, and I still remember around 2007 when I watched this video. It was great help and a great video, Thank you.

Will 28 gauge wire work?
vicmendoza11 4 months ago
@vicmendoza11 #28 works great. Any larger than that and your coil starts getting too thick. You don't want the outer turns to be too far away from the magnets.
wbeaty 4 months ago
is 300 turns of the wire around the box the most efficient? or could you generate more power by doing 400 or 500 turns?
MrLoganMohr 4 months ago
@MrLoganMohr See the project article, especially the Debugging section.
Yes, add 2x or 3x more wire. That way you won't have to spin the magnets nearly as fast.

i thought that in order for a copper wire to have current from a magnet it needed and iron core and that the solenoid had to be in the middle of a north and south pole magnetic attraction for it to work
kobe1bryant1fan 4 months ago
@kobe1bryant1fan The coil just has to enclose a strong, fast-changing magnetic field. In other words, the magnets act like the iron core. The rotating magnets supply the changing N and S poles.

What is the Formula for calculating the energy output (volts and amperes) with a specific number of coils and strength of a magnetic field?
mickycheese27 5 months ago
Does spinning a magnet inside a coil create any resistance? not counting the axle friction, if not then if there weren't any air or friction the magnet could spin infinitely?
Allexxx96Reloaded 5 months ago
@Allexxx96Reloaded Yes, read the main project article "FEEL THE ELECTRONS." This resistance is maximum when the coil is shorted, and zero when the circuit is open.
This same resistance can create a magic trick. If you drop a magnet down a copper pipe, it will appear to levitate in the middle of the pipe, and fall very slowly.

@wbeaty Thanks for the good answer I didn't even think of that copper pipe - magnet experiment lol

somerc897 5 months ago
So, you're spinning the magnets to make the diode glowing. So... magnets make coil's electrons running from one side to second one, right thru diode. Well you don't have to use your arms, just have to make your magnets running by themselves. They are magnets, allright ^^?

I was wondering if one could use rubber material for the casing? Would rapping the copper around it cancel the magnetic effect inside of it passing threw? Thanks for your time
Tumlock 5 months ago
@Tumlock yep, rubber or plastic or wood is just fine. Don't make it too thick though. The coil of wire must hug the magnet closely. If your box is too thick, then you'll need to add lots more turns of wire.
wbeaty 5 months ago
if you put more than 200 turns of copper wire will it be better or it doesn´t matter?
shusher0099 5 months ago
@shusher0099 Well you will get more electrons running around :-).
EsamoKoram 5 months ago
@shusher0099 more turns of wire gives you higher voltage output. With higher voltage, you won't have to spin the magnets so darned fast. And it's easier to light up a red LED instead of a weird special tiny bulb.

@SyedRayeed The strong magnets grab the nail with many pounds of force. Slide them around to get them centered. Stuff some bits of cardboard in the gaps on each side of the nail.
wbeaty 5 months ago
@aidan456456 If you haven't built a generator, first follow instructions exactly. Get it working right. That way you know what's needed.
After you have a working generator, try making changes and see what happens.

what would the amperage and voltage be if you added a neodynium magnet?
geekatzombies4life 5 months ago
@geekatzombies4life Neo magnet strength is about 10X stronger than ceramic. So, if you used four large rectangle neo magnets, then the volts/amps would be 10X higher, and maximum possible power output would be 100X higher. (But this doesn't work if you use a tiny neo magnet!)
wbeaty 5 months ago
@wbeaty when you mean the max power output you mean ........ because i doubt a little ting like this could produce around 3. amps or 70 volts with neodymium

can any one tell me the power of a magnet and no of turns it wud take to generate 5v of energy??
792sandy 5 months ago
@792sandy It normally puts out about one volt. So for 5V, just spin the magnets 5X faster.
Or you could wind 250 X 5 turns of wire (about 1300 turns, but more is better.)
wbeaty 5 months ago
@wbeaty hmmm thanks :) hey if your rotating a magnet instead of a coil.wat is the formula to find induced emf?? is it the same e = B l v ?
this is a way i found out but don't knw it's correct r not.since emf induced is rate of change in flux, I multiplied the field strength B with the rate of change in area i.e. L x v . So i thought of finding the area of magnet and multiplying it to the number of rotations per sec to get the change in area. am i right in this? if not plz tell the right way

nigel738 5 months ago
@nigel738 glue some stacks of magnets side by side, so they repel. (Repelling magnets all have N or S on the same end. Attracting stacks are no good, since the poles cancel out.)
Or just use a five pound $100 neodymium hockey-puck magnet ...if you want to DIE!!!

What gauge of wire do you need?
sportsgenius02 6 months ago
@PACIFICFL0W the generator only creates about one volt AC. To get more, you'd have to step it up.
Transformers can step up AC, but the generator would have to spin faster than 2000rpm. Transformers don't work if the AC frequency is too low.
wbeaty 6 months ago
@PACIFICFL0W A generator is like a wheel and drive belt. But the belt is made of electricity. When you crank the wheel, it makes the electricity flow.
If we had a drive belt and two pulleys, couldn't we use some gears to connect the second pulley to the first one? Then it would start cranking itself! It would go faster and faster, then EXPLODE. It's a Mechanicity Bomb. Don't build a drive belt assembly. You could wipe out your neighborhood.
Same deal with motors and generators.
