Question

At a point on the right bisector of a magnetic dipole, the magnetic : (A) potential varies as (1/r2) (B) potential is zero at all points on the right bisector (C) field varies as r3 (D) field is perpendicular to the axis of dipole

Tardigrade Admin · Accepted Answer

Magnetic field at P due to north south pole can be resolved into components parallel to the axis of the dipole and along the bisector. Components along the bisector cancel' out: The horizontal components add up

Q. At a point on the right bisector of a magnetic dipole, the magnetic :

potential varies as $\frac{1}{r ^{2}}$

potential is zero at all points on the right bisector

field varies as $r^{3}$

field is perpendicular to the axis of dipole

Magnetic field at $P$ due to north & south pole can be resolved into components parallel to the axis of the dipole and along the bisector. Components along the bisector cancel' out: The horizontal components add up
