Expert Solution

Given, Initial area of the wire loop ( ) =

Final area of the wire loop ( ) =

Time interval for the change in area ( ) =

Magnitude of the magnetic field ( ) =

Change in the area of the wire loop ( ) =

The magnetic flux passing through the loop ( ) =

Change in the magnetic flux passing through the wire loop ( ) =

We know that emf induced in the wire is the negative of rate of change in the magnetic flux passing through the loop.

So, induced emf in the wire ( ) = ,
