How to 𝑚𝑎𝑘𝑒 𝑎 electrical circuit electric magnet

You will need:

• An iron nail (a large one works best)
• Insulated copper wire (about 1-2 feet)
• A battery (a D-cell or AA battery)
• Wire strippers or scissors

Using wire strippers or scissors, carefully remove about an inch of insulation from both ends of the copper wire.

Start at one end of the nail and tightly wrap the insulated part of the copper wire around the nail, leaving the stripped ends free. Wrap the wire in the same direction, creating coils. The more coils you make, the stronger your electromagnet will be. Make sure the coils are close together but not overlapping too much.

Take the stripped end of the wire and connect it to the positive (+) terminal of the battery. Take the other stripped end of the wire and connect it to the negative (-) terminal of the battery.

Once the wire is connected to the battery, the nail will become an electromagnet. You can test its strength by seeing if it can pick up small metal objects like paper clips or staples.

When you are finished testing, disconnect the wire from the battery to turn off the electromagnet.
