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

Material getting magnetized of atomic magnetic moment in external magnetic fields are

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 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 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 magnet makes 55 vibrations in one minute where horizontal component of earth's field is 0.36G. If the moment of inertia of the bar magnet is 10^-5 Kgm^2 , find the magnetic moment of the bar magnet.

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
