Question

how does a electromagnet work

Answer 1

This force works both ways – a moving magnetic field creates electric current. ... The magnetic field gets weaker farther from the wire. Coiling the wire makes for a much more efficient electromagnet, because inside the coil the magnetic fields of many portions of the wire are concentrated into a small space.

Answer 2

When electric current is passed from a conductor electric field is generated around it . it is known as electro magnet . higher the intensity of current flowing through the conductor higher the magnetic field produced ..
