The time period of oscillation of a magnet in a vibration magnetometer is `1.5` seconds. The time period of oscillation of another of another magnet similar in size, shap and mass but having one-fourth magnetic moment than that of first magnet, oscillating at same place will be

Time period of oscillation of a magnetic needle is

The period of oscillation of a magnet in a vibration magnetometer is 8 seconds. The period of oscillation of magnet whose magnetic moment is four times that of the first magnet is :

The period of oscillation of a magnet in vibration magnetometer is 2 sec. The period of oscillation of a magnet whose magnetic moment is four times that of the first magnet is

The perio of oscillation of a magnet in vibration magnetometer is 2 sec. The period of oscillation of a magnet whosr magnetic moment is four times that of the first magnet is

The perio of oscillation of a magnet in vibration magnetometer is 2 sec. The period of oscillation of a magnet whosr magnetic moment is four times that of the first magnet is

A small magnetic needle is set into oscillations in a magnetic field B obtain an expression for the time period of oscillation.

The period of oscillation of a vibration magnetometer depends on which of the following factors? where I is the moment of inertia of the magnet about the axis of suspension, M is the magnetic moment of the magnet and H is the external magnetic field

A magnet has time period of oscillations T in earth's magnetic field at a place. If it is replaced by a magnet of magnetic moment six times the magnetic moment of the original one, the time period at the same place will be

Two bar magnets of the same length and breadth but having magnetic moments M and 2M are joined with like poles together and suspended by a string. The time of oscillation of this assembly in a magnetic field of strength B is 3 sec. What will be the period of oscillation, if the polarity of one of the magnets is changed and the combination is agnain made to oscillate in the same field ?
