Two bar magnets A and B are placed one over the other and are allowed to vibrate in a vibration magnetometer. They make 20 oscillations per minute when the similar poles of A and B are on the same side, while they make 15 oscillations per minute when their opposite poles lie on the same side. If $M_{A}$ and $M_{B}$ are the magnetic moments of A and B and if $M_{A} > M_{B}$ , the ratio of $M_{A}$ and $M_{B}$ is

Detailed Solution

Ratio of magnetic moments of two magnets of equal size when in same and different position is

$\frac{M_{A}}{M_{B}} = \frac{T_{d}^{2} + T_{s}^{2}}{T_{d}^{2} - T_{s}^{2}} = \frac{v_{d}^{2} + v_{s}^{2}}{v_{d}^{2} - v_{s}^{2}} \frac{M_{A}}{M_{B}} = \frac{20^{2} + 15^{2}}{20^{2} - 15^{2}} = \frac{400 + 225}{400 - 225} M_{A} : M_{B} = 25 : 7$
