What is an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
A solenoid produces an electromagnetic coil more commonly called a Solenoid. Then every length of wire has the effect of electromagnetism around itself when an electrical current flows through it.
The direction of the magnetic field is dependent upon the direction of the flow of current.
Coils that are wrapped around magnet parts make up the electromagnet.
