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...
4. Close the switch and try to pick up the same paper clips and tacks. What happens? You can increase the power of your electromagnet by winding more turns of wire around the nail. You could also use transformer wire with an enamel exterior to get more wraps around the nail....

Tape or glue the coil to the core. Then, cut the wire free from the spool, leaving 6 inches hanging off. You now have an electromagnet with several inches of extra wire at each end. Step 4 Strip the ends of the wires bare. One of the easiest ways to do this is to burn the last...
For example, an intruder might break through a window, so you could make the glass itself a circuit. The easiest way to do this is run a current through a thin line of foil wire affixed to the surface of the glass. If a burglar breaks the glass, the circuit is broken, and the ...
The basic circuit breaker consists of a simple switch, connected to either a bimetallic strip or an electromagnet. The hot wire in the circuit connects to the two ends of the switch. When the switch is flipped to the on position, electricity can flow from the bottom terminal, through the ...
How does electromagnetism make a motor move? The basic idea of an electric motor is really simple: you putelectricityinto it at one end and anaxle(metal rod) rotates at the other end giving you the power to drive a machine of some kind. How does this work in practice? Exactly how do...
Thecoilpins control the switch, and theNC,NO, andCOMpins make up the switch. Inside a relay, there is an electromagnet, a switch, and some mechanical parts to change the state of the switch when the electromagnet is turned on. Here are the main parts inside the relay: ...
The AC current in the primary winding creates an alternating magnetic field in the iron just as it would in an electromagnet. The other winding, known as the secondary winding wraps around the same iron core. In the secondary winding the magnetic field in the core creates current. The ...
