Tose Proeski-The Hardest Thing

i lov this video it make me dance

Ebay is where i get my magnets. Try there.

dude u rock

> And....nothing. Help!

It might work if you stack up lots of disk magnets to form a two-inch rod, where the magnetic poles are at the ends of the rod. Then glue on a crosswise center axle so the rod flips end-over-end when you spin it.

And the ends of the rod must be *very* close to the wire. That's why it's best to build the spinning magnets into a close-fitting box, then wind the wire outside the box.

> And....nothing. Help!

I've never built a generator like that, so I can't say what's wrong. If I had to guess, I'd say that the magnets are way way way too short, so all the field stays near the magnets and very little touches the wire. Also, with several magnets on a cardboard disk, their fields will cancel out. You need one long magnet. Also, the wire should not look like a circular ring, it should be squashed, so the hole in the ring is like a slot.

I am attempting to make a simple generator. Here's what I've done so far. I have coiled 3 spools of 30 gauge wire around a cylinder, removed the coil and taped it with electrical wire in the shape of a ring. On a piece of cardboard, I have hot glued 8 magnets around the edge of the cardboard. I'm using neodymium magnets with a pull of 24lbs each. I hooked a 25 ma 1.5 volt bulb to the wires. The coil is fixed in a box with the magnets spinning in front of the wire. And....nothing. Help!

WBeaty Sir I am in trouble
Cause where i live here is only 1cm x 1cm x 4.50cm magnets are available i have checked every shop every thing but i didn't find these size magnets and also i can't buy these magnets from radio shack cause here is no service available of radio shack so can u please tell me can these magnets work or not? and other size which u can tell me? or any other idea please please please i'll be very tankfull to you my exhibition day is very near

> how can motor be a generator?

Suppose you have two pulleys and a leather belt wrapped around both. The first pulley is the generator, and the belt is like the "electricity" inside the closed circuit of wire. The second pulley is the motor. If you turn the first pulley, this causes a "leather current." And the second pulley turns also.

See what's happening? Pulleys are electric/mechanical converters. They're neither generators nor motors, but are both.

All generators are motors!

oops..generators convert mechanical to electrical..sorry

how can motor be a generator? motors convert electrical to mechanical energy. and generators convert electrical to mechanical energy.

thanks

nice job

thats exactly correct ive almost run a set of computer speakers with this thing but i had a drill turning the pulley lol i could have just hooked the drill battery to the speakers would have worked much better the drill battery is 12 volts 2.0 amps

> and now if you spin the pulley the light lights up

Yes, small DC brush-motors are the same as generators. And they're designed MUCH better than the Simple Generator above. They have close-fitting iron parts that give much higher voltage. And they have a rotating switch that converts the coil's AC output into DC.

If you want to make a waterwheel generator or a windmill, then a DC motor is probably a better choice. (But then you didn't build it all yourself.)

I have this 9 volt DC motor and pulley assembly connected via belt and i put wires from the motor and hooked an LED on the end of the wires and now if you spin the pulley the light lights up

i got a battery and a metal wire and i burnt myself,i also licked a D battery. P.S it hurt quite a bit.lol

> so i am doing a project on tesla

I suggest buying a CCFL fluorescent light from coolerguys com/cathodes html They are run by Tesla coils. You can even cut and remove the ground wire from the fluorescent tube, yet the tube will still light up. It demonstrates Tesla's high-frequency "one wire technology" where no complete circuit is needed.

do you live in a cardboard box?

finally i can power my house for free!!!!

so i am doing a project on tesla and alternative currents, is doing this experiment good to show off the ac current, or do you have more suggestions?

i did this 4 science fair

> can you run a curent through the solenoid and make the magnets spin?

Yep. Read the webpage article, the part about "Motor Challenge." You could apply a low frequency AC wave, then spin the magnets until it "locks on" and spins by itself. Or you could supply an electric switch attached to the shaft, where the switch turns a battery on and off, creating AC to power the coil.

> how many amps and voltage does it produce?

It's AC. But it's a science fair experiment. You have to measure the output yourself. If this was just a physics demo, and not intended for science fairs, then I *would* supply every bit of detailed information.

how many amps and voltage does it produce?

Is it DC or AC current?

> so the water wheel will power it instead... Any ideas?

It needs to spin extremely fast, so a waterwheel probably won't work unless you have bearings and gears. Or you could blast it with a nozzle on a garden hose.

Great job, just one question, if you transform mechanical energy into electrical energy, can you run a curent through the solenoid and make the magnets spin?
