The magnitude of magnetic fields at a distacne 'r' from the centre of a short bar magnet, in longitudinal position to transverse position is in the ratio
4:1
2:1
1:4
1:2
Solution
For longitudinal positions magnetic field will be $B_{1} \alpha \frac{2 M}{d^{3}}$
For transverse positions magnetic field will be $B_{2} \alpha \frac{M}{d^{3}}$
$\therefore \frac{B_{1}}{B_{2}}=2: 1$
