Simply so, what is electromagnet and its uses?

Electromagnets are used in all kinds of electric devices, including hard disk drives, speakers, motors, and generators, as well as in scrap yards to pick up heavy scrap metal. They're even used in MRI machines, which utilize magnets to take photos of your insides!

how is an electromagnet made? When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet . A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply. wrapping the coil around a piece of iron (such as an iron nail)

Keeping this in consideration, what is an electromagnet example?

Devices with Electromagnets When electric current flows through the wire, it causes the coil and iron bar to become magnetized. An electromagnet has north and south magnetic poles and a magnetic field. Some other examples include hairdryers, CD players, power drills, electric saws, and electric mixers.

What is an electromagnet and how is it made?

electromagnet: A magnet made of an insulated wire coiled around an iron core (or any magnetic material such as iron, steel, nickel, cobalt) with electric current flowing through it to produce magnetism. The electric current magnetizes the core material.
