A circular disc of radius 0.2 meter is placed in a uniform magnetic field of induction 1/π (Wb / m²) in such a way that its axis makes an angle of 60⁰ with B⃗. The magnetic flux linked with the disc is:
Options
(a) 0.02 Wb
(b) 0.06 Wb
(c) 0.08 Wb
(d) 0.01 Wb
Correct Answer:
0.02 Wb
Explanation:
Here B = 1/π (Wb/m²) θ = 60⁰
area normal to the plane of the disc
= πr² cos 60⁰ = πr²/2
Flux = B x normal area
0.2 x 0.2 / 2 = 0.02 Wb
