simple Generator High school Physics project Ravish Generate electricity Manually Faradays Law

[mrhydeish]

Thank you

[08jhayar08]

how much is the total cost of this project ?? i need your response as soon as possible SIR .. thank you ..

[raveeshakh]

The components I have used are 1. Insulated copper wire -40 gauge -500grams 2.Iron nail 3. Light emitting diode (LED) 4.Strong magnet.

[MrAquadan]

can you email me the names of every thing you used?

[raveeshakh]

When we move the coil keeping the magnet at rest, the same amount of voltage would be induced.what matters is the relative motion.

[pigeonsWock]

...???????

[kingfaisal550]

what would be the result when you make magnet staionary and move your coil...........? plz answer me about that

[kdmestr]

Dear Sir,I tried this with plastic spool with a LED lamp(rating 2V) and strong magnet of loudspeaker(horn type). I used 1kg of 25gauge wire. But bulb did not burn at all. LED that works with 0.5 volt is not available in Kochi. Can we use ordynary torch bulb? Is an iron rod must for winding? Shd the winding be compact? Shd we apply varnish after winding? Pls help. Urgent.

[raveeshakh]

YES ,connect both the ends to an LED.You need a strong magnet.

[yusufrishab1]

How can electricity be passed without any current ?

Is it just coiling the copper wire and connecting both ends to the LED ?

[HomoSapien2012]

I have 6 magnets disk shaped very strong 1 inch in diameter would they work ?

[prashantdvful]

@HomoSapien2012 yes

Hi,

If I use 10 magnets and 10 coils can that generate 50 volts?

Thanks

[raveeshakh]

Either more magnets or the coils has to be increased.See, I used a coil of 60,ooo turns and a big size magnet(diameter 10cm),I could manually generate 14 volts and current was low(500milli ameres).so 50 volts is too much and difficult.But try.

[DrKillaser]

im here because of Michio Kaku (co-founder of string theory and author of several books such as physics of impossible)... i love physics, but i feel god damned stupid when i remember that Michio for his high school project built an atom smasher with magnetic field stronger than earth's by 30,000 times.. o.0... sure his electric circuits in his house exploded as he said... but that project made him win a free study in Harvard... lucky.. >:(.i really love physics and know much more than my grade10

[DrKillaser]

@DrKillaser but still feel my self so stupid.. cause im in high school too and nearly have no idea how did he do that.. o.0

[Unguidedone]

does it have an iron core? or just wire?

[raveeshakh]

Yes ,A ferrite rod is used as core.

[Unguidedone]

@raveeshakh thanks : )

[Unguidedone]

@Unguidedone thanks

[Unguidedone]

@Unguidedone ya i replied to myself ahahahah - that just happened lol....

[watchm0de2]

what's the difference between copper and magnet wire? what wire should be used in this?

[raveeshakh]

Copper wire has to be used.Probably,some may call the copper wire as magnet wire.

[Rotitomato]

@watchm0de2 You can not use copper wire without insulation. Magnet wire is copper wire but with a transparent film or a colored film on it. Without this insulating film yout coil will short out.

I have a question could I use this for making my ion cannon. Do you think if I took a induction coil and I connect a copper wire to anothere induction coil the size of a big soffa would it create a terrawat spark please reply because I am really making this!

[raveeshakh]

The magnitude of voltage generated depends on the number of turns,strength of magnetic field,numberof rotations per second etc.So without those details I am unable to estimete.

[martinzwanenburg]

@117Alfonso

than you need a truckload of copper :P

and one hell of a magnet!

good luck!

[117Alfonso]

@martinzwanenburg true but I think should change the name though. Like lightning generator. I don't know where the heck can I find a truckload of copper

[ZehaasSram]

Thank you! Your explanation is beautifully simple. I am not an expert, but I will use your information to build a wind-powered generator. Dost, Buhut shukria.

[twicegirl]

i have 2 questions.... "change in magnetic flux linking with a coil induces a voltage in the coil"

1- how can we make a change in the magnetic flux?

2- is there any other way we can make this work without winding the coils?

[raveeshakh]

1. Magnetic flux linking with a coil changes when magnet or the coil is moved relative to other.In my video,the coil is at rest(left hand), magnet (right hand)is being moved.As the magnet is moved towards or away from the coil, the magnetic field lines linking with the coil increase or decrease (as the seperation distance between changes).

2.See Faradays law can be tried with coil and magnet.I do not know any method of doing this experiment without a coil.

[twicegirl]

@raveeshakh well explained..thanks :)

[posiedon120]

@twicegirl change in magnetic flux can be done by either moving the coil towards and away from the magnet or by moving the magnet towards or away from the coil.It can also be done by rotating a "rectangular coil" between two opposite magnetic poles.

Practically, the answer to your second question is NO. (I am excluding the concept of SOLAR ENERGY)

[magga94]

dude you look exactly like Pedro from Napoleon Dynamite! ;D

[rakeshsingh35793]

I have become your Fan.. I much appriciate.. if you keep on posting such vedios. Thanks.. I spoke to you regarding the Telescope aswell, you said you would give me the BITs no.

Take an iron nail of length 10cm.take 1/2 kg 36 gauge copper wire and wind it.connect an LED to the ends of the wire.Take a big magnet(it should be atleast 10cm wide. Then move the magnet near the coil.The LED glows.

[CapNudillos]

@raveeshakh Hi, but, wich one is the + and the - ??

[raveeshakh]

Here alternating current (AC) is produced.Its direction keeps oscillating.So we cannot fix a specific terminal as + or - .However the instantaneous direction of the current can be obtained by Lenz's law.

[ppsjsh]

that was pretty cool thanks for the info. nice job.
