A uniform magnetic field of `0.08 T` is directed into the plane of the page and perpendicular to it as shown in the figure. A wire loop in the plane of the page has constant area `0.010 m^(2)`. The magnitude of magnetic field decrease at a constant rate of `3.0xx10^(-4)Ts^(-1)`. Find the magnitude and direction of the induced enf in the loop.

Text Solution

Verified by Experts

The correct Answer is:
`3 muV`, clockwise
`phi=BA`
`e=(dphi)/(dt)=A(dB)/(dt)=0.1xx3xx10^(-4)=3muV` since main flux is decreasing so induce flux will be in same direction so current is clockwise direction.
