you need a large iron nail, 90 cm in a thin copper wire - I stress: a. thin - insulation, R20 batteries and an extra piece of pipe
tape measure around 20 cm 90. cm piece of wire from that point, Begin to wrap the wire around the large iron nails, try to make turns hitting each other Note: .... wire insulation should be fine otherwise, may not work electromagnet
remaining wires, if necessary, a little trim, but leave a piece of the other end. Carefully remove the insulation from both ends of the wire, but only for a short length.
Wrap one end of the insulated wire around the protruding positive terminal of the battery. if necessary secure it with electrical tape. Put the other end to the negative pole. Secure with electrical tape. Be careful, the wire can quickly make a very hot.
electromagnet ready. You can even wrap it with electrical tape in the middle.
