The magnetic needle of a V.M.M completes 10 oscillaitons in 92 seconds. When a small megnet is placed in the magnetic meridian 10cm due north of needle with north pole towards south completes 15 oscillations in 69 seconds. The magnetic moment of magnet

A magnetic needle has magnetic moment 5.8 x 10 A m and moment of inertia of 7.8 x 10 kg m', it performs 12 complete oscillations in 6.0 s. What is the magnitude of magnetic field?

The magnetic needle of an oscillation magnetometer makes 10 oscillations per minut under the action of earth's magnetic field along. When a bar magnet is placed at some distance along the axis of the needle it makes 14 oscillations per minute. If the bar magnet is turned so that its poles interchange their position, then the new frequency of oscillation of the needle is:

A small magnetic needle performs 10 oscillations/minute in the earth's horizontal magnetic field . When a bar magnet is placed near the small magnet in same position , frequency of oscillations becomes 10sqrt2 oscillations/minute . If the bar magnet be turned around end to end , the rate of oscillation of small magnet will become

The combination of two bar magnets makes 10 oscillations per second in an oscillation magnetometer when like poles are tied together and 2 oscillations per second when unlike poles are tied together. Find the ratio of the magnetic moments of the magnets. Neglect any induced magnetism.
