Question

Inside a current carrying solenoid the magnetic field of force are

Answer 1

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Even small solenoids can exert forces of a few newtons.

Answer 2

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. ... The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.
