Question

The reading of deflection magnetometer is more accurate when $\theta$ lies between

• A. $0^o$ and ${30}^o$
• B. ${30}^o$ and ${60}^o$
• C. ${60}^o$ and ${90}^o$
• D. any angles

Answer 1

The correct option is B ${30}^o$ and ${60}^o$

The deflection magnetometer is more accurate when it is at the deflection of ${45}^{\circ }$ and hence the reading must be between ${30}^{\circ }$ to ${60}^{\circ }$ for obtaining the accurate values or outputs.
