Two short bar magnets of magnetic moment M each are placed as shown in diagram. The centre of both the dipoles lies along the same line as P. The magnetic field at P is given by (K = $μ_{0} /4 π$ ):-

Options:

Answer:

Solution:

The fields due to the two dipoles at P are perpendicular.

$B_{axial} = \frac{2 K M}{d ^{3}}, B_{equatorial} = \frac{K M}{d ^{3}}$

$B = B_{axial}^{2} + B_{equatorial}^{2} = \frac{K M 5}{d ^{3}}$
