EXPERIMENT : POWERFUL MAGNET AND MATCHSTICKS #shorts

A bar magnet is put on the hanger of oscillation magnetometer and is made to oscillate in earth's magnetic field. Frequency of oscillation of bar magnet is found to be 3 Hz at a place where horizontal component of earth's magnetic field is 25 muT . Now a short magnet is placed to the north of magnetometer in such a manner that its North Pole points towards north. Distance of short magnet from the bar magnet hanging inside the magnetometer is 1 m. Frequency of oscillation now becomes 6 Hz. What is magnetic moment of short magnet?

Find the magnetic force on a short magnet of magnetic dipole moment M_(2) due to another short magnet of magnetic dipole moment M_(1) .
