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?
A
No current induced
B
abcd
C
adcb
D
The current will reverse its direction as the electron goes past the coil
Detailed Solution
As the electron approaches, the magnetic flux through the coil increases and a current is induced (in the direction abcd).
As the electron moves away, the flux through the loop decreases, so the induced current reverses its direction.
As the electron moves away, the flux through the loop decreases, so the induced current reverses its direction.
