What is an Electromagnet? Give names of two devices where they are used
Answers
Explanation:
Magnets are cool. There are all kinds of fun experiments you can do with them, but their usefulness can be rather...limited. A magnet is always a magnet. It always attracts. Sometimes you want that, such as with a fridge magnet, but not always. By using electromagnets, that all changes, and the applications become endless.
An electromagnet is a magnet that is created using an electric current, created by electricity. Since electricity can be turned on and off, so can an electromagnet. It can even be weakened or strengthened by decreasing or increasing the current.

electromagnets are very widely used in electric and electronic mechanical device including:
- motors and generator.
- Transformers
- relays
- Electric bells and buzzer.
- Loudspeaker and headphones.
- Actuators such as valves.
- magnetic recording and data storage equipment: tape recorders, VCRs, hard disks.
- MRI machine.
an electromagnet is a type of magnet in which the magnetic field is produced by an electric current fullstuff the magnetic field disappears when the current is turn off for stuff in electromagnetics usually consists of a large number of closely spaced turns of wire or coil that create the magnetic field.
