how does an electromagnet work ?
If u answer properly i will surely mark you as brainliest

Answer 1

Answer:

Electromagnets are a different from permanent magnets. Electromagnets are made of coils of wire with electricity passing through them. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet. When the electricity stops flowing, the coils don’t act like a magnet anymore. Electromagnets are used in a lot of electronic devices when magnetic forces are only needed for short periods of time.

Answer 2

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. ... The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
