In Fig. 30-33, a circular loop of wire in diameter (seen edge-on) is placed with its normal at an angle with the direction of a uniform magnetic field of magnitude . The loop is then rotated such that rotates in a cone about the field direction at the rate ; angle remains unchanged during the process. What is the emf induced in the loop?

Answer:

there is no induced emf developed

Explanation:

Induced emf developed in the circular loop

ε= [tex]-\frac{d\phi}{dt}[/tex]

The magnetic flux developed in the coil is

[tex]\phi =BANcos\theta[/tex]

[tex]\epsilon= -\frac{d(BANcos\theta)}{dt}[/tex]

[tex]\epsilon= -BAN\frac{d(cos\theta)}{dt}[/tex]

Here angle made by the loop with   the field remaining constant

[tex]\frac{d cos\theta}{dt}[/tex] = 0

[tex]\epsilon= -\frac{d}{dt} (0)[/tex]

hence there is no induced emf developed
