Electro Magnetic Induction And Alternating Currents Question 329
Question: Two identical coaxial circular loops carry current i each circulating in the clockwise direction. If the loops are approaching each other, then [MP PMT 1995, 96]
Options:
A) Current in each loop remains constant
B) Current in each loop remains the same
C) Current in each loop increases
D) Current in one loop increases while in the other it decreases
Show Answer
Answer:
Correct Answer: C
Solution:
According to Lenz’s Law, the direction of the induced electromotive force (emf) and current will be such that it opposes the change in magnetic flux that produced it.
