Magnetic Field Due To Current Carrying Solenoid

Magnetic lines of force inside a current carrying solenoid are

Magnetic lines of force inside a current carrying solenoid are

A: If a bar magnet is cut into two equal halves then magnetic dipole moment of each part is half that of the original magnet. R: magnetic dipole moment is the product of pole strength and magnetic length.

The magnetic field due to a current-carrying solenoid is independent of
