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

1. adcb.
2. the current will reverse its direction as the electron goes past the coil.
3. no current induced.
4. abcd.

Solution

When ${\mathrm{e}}^{-}$ comes closer the induced current will be anticlockwise
When ${\mathrm{e}}^{-}$ comes farther induced current will be clockwise.
