Position the wire so that it’s perpendicular to the iron core and at one end.

It’s essential that the wire is wrapped in the same direction so the electricity flows in one direction. If you wrap the wire in different directions, the electricity will flow in different directions, and you won’t create a magnetic field.

The more wire you use, the stronger the electrical current, so be careful and use caution when creating your magnet.

As you remove the insulation, the wire will turn from the copper color of the insulation to the natural silver color of the wire.

Curling the ends of the wires helps the battery maintain good contact with the wire.

Position one wire end at the negative end of the battery and the other wire end at the positive end of the battery.

If the battery becomes hot, use a small towel to hold the wires to the battery. When you’re finished using the magnet, detach the wire ends from the battery.

Do a little research before picking out a larger battery pack to be sure you’re picking one that’s safe and will work. The wire ends go where the positive and negative terminals are, and you can use tape to attach the wires to each end.

Wrap the wire tightly around the metal so that the electrical current conducts well. If you’re using a larger piece of metal, it’s only necessary to wrap the strand of metal with one layer of wire for safety reasons. Use electrical tape to connect the wires to each end of the battery.

Use the small piece of iron for this, such as a nail, screw, or bolt. Wrap the wire in a single direction going around the piece of iron. Tape the ends of the wires to the battery using duct tape or electrical tape.
