- AMagnetic fields
- BEarth's field
- CMagnetic moments
- ✓All of the above
✓
Answer
Correct option: D.
All of the above
d
Vibration magnetometer is used for comparison of magnetic moments and magnetic fields. This device works on the principle, that whenever a freely suspended magnet in a uniform magnetic field, is disturbed from it's equilibrium position, it starts vibrating about the mean position.
