Solenoid is type of artificial magnet in which magnetism is produced by passing current through it.It is made by wounding a conducting wire around a soft iron core.
Ways to increase the strength of magnetic field of a solenoid --->
1) To increase the number of turns of conducting wire.
2) To increase the magnitude of current.

Answer:
Solenoid is a long cylindrical coil of wire consisting of a large number of turns bound together very tightly
Features
magnetic field outside a solenoid is negligible as compared to the bar magnet
magnetic field of a solenoid can be varied as per our requirement just by changing current of law of solenoid but in the bar magnet is fixed
