The correct answer is:
2:1
For longitudenal positions magnetic field will be $B_{1} \alpha \frac{2 M}{d^{3}}$
For transverse positions magnetic field will be $B_{2} \alpha \frac{M}{d^{3}}$
$\therefore \frac{B_{1}}{B_{2}}=2: 1$
For transverse positions magnetic field will be $B_{2} \alpha \frac{M}{d^{3}}$
$\therefore \frac{B_{1}}{B_{2}}=2: 1$
