The magnetic field produced inside a current carrying solenoid is uniform.
Explanation:
A solenoid is a cylindrical coil of wire that produces a nearly uniform magnetic field, when electric current is passed through it.
The direction of magnetic field inside the solenoid will be along the axis of the solenoid and can be determined by a rule called the right hand thumb rule.
Right hand thumb rule states that, all the curled fingers of right hand signifies the flow of current in the circular direction in the coils and the thumb signifies the direction of magnetic field in the solenoid.
