Magnets can be found in the material magnetite. These natural magnets are quite weak, however; those produced artificially are much stronger. Even stronger than these are electromagnets, which are made by running an electrical current around a piece of iron. The electrical field will magnetize the...
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.Visit us at: Power Compare Batteries All Chargers Battery History Battery Care Battery Leakage...
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 go all out and create an electromagnet out of your metal that will create a magnet field that will either be attracted by or repelled by other magnets. To make an electromagnet out of your metal, wrap and coil wire around it completely and attach both ends of the wire to ...

You can magnetize them again by rubbing a magnet on it. Putting the 'Electro' in 'Electromagnet' Since you need an electrical current to operate an electromagnet, where does it come from? The quick answer is that anything that produces a current can power an electromagnet. From the small ...
In this figure, you can see that a relay consists of two separate and completely independent circuits. The first is at the bottom and drives the electromagnet. In this circuit, a switch is controlling power to the electromagnet. When the switch is on, the electromagnet is on, and it attrac...
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...
You can easily create a small electromagnet yourself by connecting the ends of a copper wire to the positive and negative ends of an AA, C or D-cell battery. This creates a small magnetic field. If you disconnect either end of the wire from the battery, the magnetic field is taken away...
2. Start Your Letter of Interest for a Job with a Hook You're the needle. The haystack is all the junk email the manager gets. How can you make sure they find you? You must learn to write a letter of interest that catches their attention like an electromagnet. You need a hook. Use...
