Hint: In order to find magnetic fields, magnetometers are used. The free bar magnet, which is pivoted in the horizontal plane, moves angularly to achieve this. It consists of a compass box with a small magnetic needle that can freely rotate in the horizontal plane after being pivoted at the centre of a circular scale. The centre of a 1 m long wooden box contains this compass box.
Complete step by step solution:
The tangent law is the basis for how a Deflection magnetometer operates. A magnetic needle rests in the direction of the resulting field when two uniform magnetic fields act on it at right angles to one another, according to this law.
A vibration magnetometer is a device used to measure the horizontal component of the Earth's magnetic field or to compare the magnetic moments of two magnets. When a magnet hanging in a consistent magnetic field (such the one caused by the earth's magnetic field) is moved out of its equilibrium position and starts to vibrate merely harmonically about the direction of the field
The torque operating on a bar magnet and rotational inertia are the basis for how a vibration magnetometer operates. With the use of a deflection magnetometer or vibration magnetometer, the magnetic moments of two bar magnets can be compared.
Hence option C is correct.
Note: The deflection magnetometer can be used to confirm inverse square law. The deflection magnetometer can be used to determine the horizontal component of the earth's magnetic field. The magnet will not oscillate and will stop when aligned with the field if the field is weak or not uniform. Therefore, a homogeneous, weak magnetic field is required for the vibration magnetometer to function.
