solenoid is a cylindrical coil of wire acting as a magnet when carrying electric current.
Factors effecting strength of magnetic field produced in a solenoid are:-
1) strength of current:- strength of magnetic field increases if the magnitude of current passing through the solenoid is increased.
2) number of turns of wire:- magnetic field can be increased by increasing the number of turns of copper wire in solenoid
