If the moments of inertia of two bar magnets are same, and if their magnetic moments are in the ratio 14:9` and if their frequencies of oscillations are same, the ratio of the induction field strength in which they are vibrating is

Two discs of same material have the same mass. If their thickness are in the ratio 1:3 , then their moment of inertia are in the ratio

The length, breadth and mass of two bar magnets are same but their magnetic moments are 3M and 2M respectively. These are joined pole to pole and are suspended by a string. When oscillated in a magnetic field of strength B, the time period obtained is 5s. If the poles of either of the magnets are reverse then the time period of the combination in the same magnetic field will be –

A bar magnet is oscillating in a uniform magnetic field of induction 0.4xx10^(-5)T . When the frequency of the oscillating bar magnet is double due to increasing magnetic field, the increase in magnetic induction is

The ratio of time periods of oscillaiton of two magnets in the same field is 2:1 . If magnetic moment of both the magnets is equals , the ratio of their moment of inertias will be .
