Solenoid is a long coil containing a large number of turns of copper wire.
The magnetic field produced by solenoid is similar to magnetic field of bar magnet.
The strong magnetic field produced in solenoid an be used to magnetize a piece of soft iron which results in Electro magnet.
The strength of an electro magnet can be increased by:
--->Number of turns in coil:
if we increase number of turns in coil, magnetic field strength can be increased.
---> If current in the coil increases strength of magnetic field also increases.
