Direction of magnetic field at equatorial point is

Question

Direction of magnetic field at equatorial point is (A) parallel to M (B) perpendicular to M (C) making an angle of 45° with M (D) antiparallel to M

Tardigrade Admin · Accepted Answer

Magnetic field due to a magnet at any point or equatorial line is given by

B = \frac{μ _{0}}{4 π} \frac{M}{d ^{3}}

Direction of B is shown in figure.

Hence, in equatorial position, the direction of magnetic field is parallel to magnetic axis direction from north pole to south pole ie, parallel to M.
