Question 354: Electromagnetic Induction

Question

A circular disc of radius 0.2 meter is placed in a uniform magnetic field of induction $${1 \over \pi }\left( {{{Wb} \over {{m^2}}}} \right)$$ in such a way that its axis makes an angle of 60o with $$\overrightarrow B .$$ The magnetic flux linked with the disc is

Accepted Answer

Given B = $${1 \over \pi }\left( {{{Wb} \over {{m^2}}}} ight)$$
$$	heta $$ = 60
o
Area normal to the plane of the disc
= $$\pi $$r
2
cos60
o
= $${{\pi {r^2}} \over 2}$$
Flux = B ÃÂ normal area
= $${{0.02 	imes 0.02} \over 2}$$ = 0.02 Wb
