" The magnetic field on the axis at a distance "z" from the centre of the bar magnet would be? "

The dipole moment of a short bar magnet is 1.25 A-m^(2) . The magnetic field on its axis at a distance of 0.5 metre from the centre of the magnet is

The dipole moment of a short bar magnet is 1.25 A-m^(2) . The magnetic field on its axis at a distance of 0.5 metre from the centre of the magnet is

Derive an expression for the magnetic field at a point on the axis located at a distance x from the centre of a magnetic dipole of length 2l and magnetic moment M.

A short bar magnet has a magnetic moment of 0.65TJ ^(-1) , then the magnitude and direction of the magnetic field produced by the magnet at a distance 8 cm from the centre of magnet on the axis is
