Q. Ratio of magnetic intensities for an axial point and a point on broad side-on position at equal distance $d$ from the centre of magnet will be or The magnetic field at a distance $d$ from a short bar magnet in longitudinal and transverse positions are in the ratio
A) $1\ :1$
B) $2\ :3$
C) $2\ :1$
D) $3\ :2$
Explanation
(c) $B_{1} = \frac{2M}{d^{3}},\ B_{2} = \frac{M}{d^{2}};\ \therefore\frac{B_{1}}{B_{2}} = 2\ :1$
