Electro Magnetic Induction And Alternating Currents Question 363
Question: A magnet is brought towards a coil (i) speedly (ii) slowly then the induced e.m.f./induced charge will be respectively [RPMT 1997; MP PMT 2003]
Options:
A) More in first case / More in first case
B) More in first case/Equal in both case
C) Less in first case/More in second case
D) Less in first case/Equal in both case
Show Answer
Answer:
Correct Answer: B
Solution:
The magnitude of induced e.m.f. is directly proportional to the rate of change of magnetic flux. Induced charge doesn?t depend upon time.
