How can I create electromagnetism?
Creating an electromagnetic field is very simple.
All you need is:
1) Copper Wire
2) Battery (AA is suggested)
3) A nail
4) Wire Strippers (optional)
5) Tape (Electrical tape advised)
Remove the some insulation at the ends of the copper wire using the wire strippers. (Removing 4cm from each end is suggested)
Wrap the copper wire around a nail. The more you wrap the wire, the better.
Connect the 2 ends of the copper wire to the two ends of a battery and tape them. Your electromagnet is ready.
To check for the electromagnetism produced, hold the nail to a compass; the compass needle will start to spin and will point to the nail.
