Question

An electron moves on a straight line path XY as shown. The abed is a coil adjacent to the path of electron. What will be the direction of current, if any, induced in the coil?

Options

• No current induced

• abcd

• adcb

• The current will reverse its direction as the electron goes past the coil

Answer 1

The current will reverse its direction as the electron goes past the coil

Explanation:

When e^- approaches the loop, one form of magnetic flux increases, while another type of magnetic flux drops. As e^- passes through the coil, the generated current opposite will reverse its direction.
