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

Options

A. `1:1`
B. `2:3`
C. `2:1`
D. `3:2`

Answer

c

Explanation

(c) `B_(1)=(2M)/(d^(3)), B_(2)=(M)/(d^(3)), therefore (B_(1))/(B_(2))=2.1`
