Electro Magnetic Induction And Alternating Currents Question 320
Question: Two circular coils can be arranged in any of the three situations . Their mutual inductance will be [IIT JEE (Screening) 2001]
Options:
A) Maximum in situation
B) Maximum in situation
C) Maximum in situation
D) The same in all situations
Show Answer
Answer:
Correct Answer: A
Solution:
The mutual inductance between two coils depends on their degree of flux linkage, i.e., the fraction of flux linked with one coil which is also linked to the other coil. Here, the two coils in arrangement (a) are placed with their planes parallel. This will allow maximum flux linkage.
