Text Solution

Verified by Experts
The correct answer is:
C
In a vibration magnetometer, the twists of the suspension fibre can create tension and additional restoring forces that affect the motion of the magnet.
When the twists are removed, it allows the magnet to oscillate in a more free manner without interference from those additional forces.
This enables the magnet to respond more accurately to the magnetic field it is placed in, resulting in a clearer measurement of the oscillations.
Therefore, removing the twists ensures that the magnet may vibrate freely.
