Question

Write factors on which magnetic field depends in current carrying solenoid

Answer 1

Factors on which the strength of a magnetic filed produced by a current carrying solenoid depends:Number of turns in the solenoid : The larger number of turns in the solenoid, stronger is the magnetic field produced.Strength of current : The larger the current passed through the solenoid, stronger is the magnetic field 

Answer 2

1) amount of current

2)no.of turns of wire

3)core metal

4)the gap between two poles.
