Electro Magnetic Induction And Alternating Currents Question 453
Question: Two different wire loops are concentric and lie in the same plane. The current in the outer loop (I) is clockwise and increases with time. The induced current in the inner loop
Options:
A) is clockwise
B) is zero
C) is counter clockwise
D) has a direction that depends on the ratio of the loop radii.
Show Answer
Answer:
Correct Answer: C
Solution:
- As I increases, $ (\phi ) $ increases
$ \therefore $ $ I_{i} $ is such that it opposes the increases in $ \phi $ Hence, $ \phi $ decreases (By Right Hand Rule). The induced current will be counter-clockwise.
