Text Solution
Verified by ExpertsThe correct answer is:
D
The 'sum and difference method' in a vibration magnetometer is preferred for comparing magnetic moments due to several advantages:
- Step 1: In this method, we do not need to determine the moment of inertia of the magnetic system, which is involved in a direct measurement approach. This reduces experimental errors as the moment of inertia can be difficult to measure accurately.
- Step 2: Fewer observations are required since the method directly uses the resonance frequencies of the magnets rather than needing to measure multiple parameters all the time.
- Step 3: The calculations involved are simpler as the method yields results directly related to the differences in the frequencies without extensive calculations for each magnetic moment.
