Pete's Electromagnet


Hi I'm Peter and I'm going to explain how my electromagnet work's:

1) The electromagnet isn't really a magnet at all. It is a copper coil wrapt around an insulated metal object.
2) When you run electricity through the electromagnet it creates a pulse of magnetic force (as long as you keep running power through it).

To make the electromagnet you will need:
- Big nail(preferably 10cm long)
- Copper wire (silicone insulated)
- Paper
- tape
- wire clippers
- knife

Method:
1) Take the nail and wrap it in paper leaving a tip showing.
2) Take the copper wire and wrap it at least 50 times around the insulated nail.
3) Once finished tape the 2 wire ends sticking out, to the end and beginning, of at least 4 C batteries and "wallah!" You are finished.
4) Make a chain of staples to test its magnetism.
