Electromagnet is a type of magnet in which magnetic field is produced by electric current . It works on principal of electromagnetic induction . It losses it's magnetism when current is switched off .
Electromagnets are made when a large number of coils are wrapped around a piece of iron core .
Strength of magnetic field of electromagnet depends on
-number of turns .
-Magnitude of current .
