Question

A current carrying coil placed in a magnetic field B experiences a torque τ. If θ is the angle between the normal to the plane of the coil and field B and φ is the flux linked with the coil, then

• A. τ is minimum for θ : 90°
• B. τ and φ are minimum for θ : 0°
• C. φ is maximum for θ : 90°
• D. τ and φ are zero for θ : 90°
• E. τ is zero and φ is maximum for θ : 90°

Answer 1

Answer: (C)

φ is maximum for θ : 90°

Answer 2

The correct option is (C) : φ is maximum for θ : 90°
