Question

Fig shown below represents an area A = 0.5 m² situated in a uniform magnetic field B = 2.0 weber/m² and making an angle of 60° with respect to magnetic field.The value of the magnetic flux through the area would be equal to(a) 2.0 weber(b) 3 weber(c) 3/2 weber(d) 0.5 weber

Answer 1

Flux : Represented by F

Theta : Represented by ©

Now as we know , F = B.A cos©

where© is angle between B and A

B= 2 Tesla

A= .5 metre sq.

©= 60 degree

F = 2 × .5 × cos 60

F =1× cos 60

F = .5 Weber
