A circular disc of radius 0.2 meter is placed in a uniform

A circular disc of radius 0.2 meter is placed in a uniform magnetic field of induction 1/π (Wb/m^2→_B .The magnetic flux linked with the disc is:

Here,

B =	1	(Wb/m²)
	π

θ = 60°
Area normal to the plane of the disc

= πr²cos60° =	πr²
	2

Flux = B × normal area

=	0.2 × 0.2	= 0.02 Wb
