An electron moves on a straight line path 
as shown. The 
is a coil adjacent to the path of electron. What will be the direction of current, if any, induced in the coil?
A
The current will reverse its direction as the electron goes past the coil
B
No current induced
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
When the electron moves from 
to 
, the flux linked with the coil 
(which is into the page) will first increase and then decrease as the electron passes by. So the induced current in the coil will be first anticlockwise and will reverse its direction (i.e., will become clockwise) as the electron goes past the coil.
