AIPMT PRELIMS 2008 Physics Magnetic Flux MCQ Question

Type: MCQ-numerical-Medium-Class 12

A circular disc of radius 0.2 metre is placed in a uniform magnetic field of induction 1πWbm2\frac{1}{\pi} \frac{Wb}{m^2} in such a way that its axis makes an angle of 60° with B\vec{B}. The magnetic flux linked with the disc is -

A

0.08 Wb

B

0.01 Wb

C

0.02 Wb

D

0.06 Wb

Correct Answer

Option C

Detailed Explanation

Magnetic flux is calculated using the formula Φ=BAcos(θ)\Phi = B \cdot A \cdot \cos(\theta). Substituting the given values yields the correct flux.
