Answer:To create your own electromagnet, you will need the following materials:
Large iron nail (approximately 3 inches in length)
Thin coated copper wire
Dry cell batteries
Electric tape
Iron fillings, paper clips and other magnetic items
Procedure
Take the 3-inch nail and the thin covered copper wire, and wrap the copper wire around the nail, leaving at least 10 inches of it at the end. Make sure you don’t overlap the wires when you wrap it around the nail. Take your scissors or cutter, and cut the wire allotting about 8 to 10 inches on the other end too.
The next step is to attach the wires to the terminals of the battery. Do this by first peeling the plastic covering off the copper wire, and attach one end to the positive terminal of the dry cell battery, and the other end to the negative terminal of the battery. Get your electric tape and tape both ends of the wire to the battery terminals to keep them in place.
Get your iron fillings, paper clips and other magnetic items available at your place then test your electromagnet.
