The dipole moment of the short bar magnet is $12.5 A - m^{2} .$ The magnetic field on its axis at a distance of $0.5 m$ from the centre of the magnet is

Options:

Answer:

Solution:

The magnetic field, $B = \frac{μ _{0}}{4 π} \cdot \frac{2 N}{d ^{3}}$ $= 1 0^{- 7} \times \frac{2 \times 1.25}{( 0.5 ) ^{3}} = 2 \times 1 0^{- 6} N / A - m$
