My daughter is planning to make a faraday flashlight for her science fair, and from her current research, it seems she will need a magnetic wire, neodymium magnet, a rectifier (is it the same as a diode bridge?), a capacitor and an LED. I just need specifics:
1.what kind of magnetic wire (thickness?),
2.size of neodymium magnet (she wants to make a pensize flashlight, if it is at all possible)
3.what kind of rectifier and capacitor (what is a 5.5 v IF electrolytic capacitor? had seen it in one of the websites...)
4. what kind LED
Also, would it matter what length the tube/pipe for the magnet is?
She was also wondering what would happen if there are 2 or 3 separate set-ups of the coiled wire in a single pipe that the magnet will pass through (i would not even know how to connect them to the capacitor!) and whether 2 or 3 magnets can be put together to increase the amount of currency produced.
This is for a 7th grade project and it does not need to be complicated. I was hoping to buy all materials and not make any capacitors/rectifiers (any suggestions on where to get them would be appreciated!) I would probably just have someone help with the soldering of any wires if needed.
Just remembered about the switch as well - where does it connect in this system?
Thanks for any information. The research proposal is due this Monday and I am in a panic!
