A wire loop of area 0.05 m² is placed in a magnetic field of 1.5 T. If the flux through the loop is 0.03 Wb, what is the angle between the field and the normal to the loop?
Q1. A wire loop of area 0.05 m² is placed in a magnetic field of 1.5 T. If the flux through the loop is 0.03 Wb, what is the angle between the field and the normal to the loop?
Answer: 66.4°
Explanation: Φ = BAcosθ; cosθ = Φ/BA = 0.03/(1.5 x 0.05) = 0.4; θ = 66.4°. Option C is wrong due to incorrect θ.
