How to Make an Electromagnet Leave about a 4” end of wire loose and then tightly wrap the wire around the nail or bolt. Wrap it as many times as possible leaving just a small amount of exposed metal at each end. The more coils, the stronger the electromagnet. Secure with tape. Leave...

You can also try increasing the size of the armature, and how many coils there are, to make a stronger electromagnet. When using batteries of higher voltage, and bare wires, be very careful. The circuit can emit enough heat to cause a burn if the wire is held too long. More Electricity...
Often, the device is essentially an electromagnet. Why Magnets Stick Magnets are attracted to materials that have unpaired electrons that spin in the same direction. Shutterstock/New Africa If you've read How Electromagnets Work, you know that an electrical current moving through a wire creates...
For example, you might want the electromagnet to energize using 5 volts and 50 milliamps (250 milliwatts), while the armature can support 120V AC at 2 amps (240 watts). Relays are quite common in home appliances where there is an electronic control turning on something like a motor or a...
