## Homework Statement

Suppose, there is a

**'constant'**magnetic field ##B## in the upward direction. A loop of conductive wire(XYZ in the picture, which is connected to a closed circuit with resistance R) is placed horizontally on it. The area of the loop is being increased with time. Will there be any current flow in the circuit?

## Homework Equations

##\mathcal {E} = -\frac{d \phi}{dt}##

##\phi = BA cos \theta##

## The Attempt at a Solution

I think, as the area is changing, there will be a current flow proportional to the rate of change of area inclosed by the loop.
