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.

The combination of two bar magnets makes 20 oscillations per minute in an oscillation magnetometer when like poles are tied together and 5 oscillations per minute when unlike poles are kept together. Then ratio of the magnetic moment of magnets is

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is 2 s . The magnet is cut along its length into three equal parts and these parts are then placed on each other with their like poles together . The time period of this combination will be
