The restoring force for a magnet oscillating in a vibration magnetometer is provided by
The restoring couple for a magnet oscillating in the vibration magnetometer is provided by
A bar magnet used in a vibration magnetometer is heated so as to reduce its magnetic moment by 19%. The periodic time of the magnetometer will :
The magnetic needle of a vibration magnetometer completes 10 oscillations in 92 seconds. When a small magnet is placed in the magnetic meridian 10cm due north of the needle with north pole towards south completes 15 oscillations in 69 seconds. The magnetic moment of the magnet (BH=0.3G) is
