Electromagnetic Induction Ques 23
23. 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
[2015 RS]
(a) adcb
(b) The current will reverse its direction as the electron passes through the coil
(c) No current is induced
(d) abcd
Show Answer
Answer:
Correct Answer: 23.(b)
Solution:
An induced current will be produced when $e^{-}$ approaches, and the induced current will be anticlockwise
when $e^{-}$moves farther induced current will be clockwise
Presence of magnetic flux is not enough. The amount of magnetic flux linked with the coil must change in order to produce any induced emf in the coil.
