How electromagnets and electric generators work:

[syprix]

thanx for the video man. I learned alot.

[HuskyMaster9000]

At around 6:10, uploader mixes the terminology "current" with "5 volts". Purely for clarification purposes to all those interested in playing with electromagnets, current is measured in amperage, and not voltage. Higher voltage does lead to higher amperage, however.. but I, for one, do not recommend it, as increasing voltage increases amperage but in turn increases watts... which will melt your magnet... try decreasing Resistance first. c:

I(current) = V(volts) / R(resistance)

P(watts) = I * V

THANK YOU FOR A GOOD DETAILED VIDEO, YOUR ABILITY TO ANTICIPATE THE NEXT QUESTION, AND THEN DESCRIBING IT , IS A GOOD TEACHING APPROACH.

Very nice video! Thanks!

[speedbumphu]

Yo! First when you started to clap I thought this gonna be a revolutionary RAP style tutorial for electromagnets:) Great video Bro, thanks for posting!

If you're spending time trying to make magnet motors, then that is absolutely proof that you have absolutely no idea how magnets *ACTUALLY* work !

[muddboy3476]

Right hand rule is the olddd way, it's the left hand rule now! Electricity runs from negative to positive.

Lord have mercy..this boy is GOOD LOOKING !!

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

[fawkUtube]

Thanks for the info. =)

can you cut the soft iron smaller than 6 inches like maybe 3 , 2inch pieces and still have enough space to make a good enough coil? and how do you magnetize the iron? Or get electricity to it rather... I'm pretty new at this subject but i am like a sponge and take it in and hold it all. Would be interested if it would be possible to magnetize the iron just as it started to pass a stationary magnet as to pull toward it and then let go so the next one could do the same.

Very Informative

Very Imformative

[PianoMastR]

how can you tell the difference between soft iron and "normal" iron just by looking at it?

what if i were to stack several layers of iron or soft iron on top of each other? would that decrease increase or have nothing to do with the strength of the magnet? maybe it gives the magnet more "torque" but the same "speed" (just an idea)

and you kind of lost me from 3:21 to 3:31 and from 4:05 to 4:23. thank you

btw i am very interested in all of this stuff and more keep doing what you do

[morbideddie]

pretty informative. you were wrong about the soft iron though. soft iron is iron with a low carbon content. iron with a high carbon content is called steel as you know. you were probably thinking of laminated cores that use thin strips of iron basically stuck between thin sheets of silicone as this reduces eddie currents being formed hence reducing energy losses

[333kgb]

Hi, thanks for the info, but im still stuck, wondering whats going on in the quantum world. I spin the rotor and two magnets always stop off center of the core. If I put the rotor closer to the core then one magnet stops directly over the core. But the dam thing just wont keep spinning. any pointers?

[laughing31]

i just got into researching this stuff so apologies if this is a dumb question.. but what how is this relevant to electric generators?

[chainsawmonk]

Fucking magnets, ho- Oh wait this is how they work, thx!

[Ronaldo707071]

thanx u pretty much did science assessment for me...cheers ;)

[zestclean]

What is the % of silicon + others elements in these rods?

I'm finding it hard to find soft iron so I'm looking into getting some if you still have any available. Also, what is the mass of the bar?

[TrEnergon]

i knew nothing about magneticism except the fact that umm the are magnets lol so you have taught me alot sir thank you very much

[arthus1971]

did you know the formula for build coils?

[xxhukkoxx]

Holy shit this is awesome!

Thank you so much!

[ihavnothingbetertodo]

dorothy93 you're the one that's watching this video to learn something and if he's flawless in his explanation except for one term you should probably shut the hell up

[jzsd14me]

My goodness, THANK YOU!

[TamilMYSTIQUE]

heeey can you please tell me where we can buy a soft iron core

or what could be used as one

please lpease help

[dorothy93]

its an atom, not a molecule dumb ass.

[jzsd14me]

Thank you for the constructive correction. My fault. I was going for the concept more than the terminology. Golly, gee! I hope I didn't ruin your day.

[jolres]

Come on man, post your work (videos) with free energy motors. It's fun to watch them, even if you do not succeed.

[jzsd14me]

I've got the next one almost ready. Soon, young jedi.
