Electro Magnetic Induction And Alternating Currents Question 291
Question: Assertion : The induced emf in a conducting loop of wire will be non zero when it rotates in a uniform magnetic field. Reason : The emf is induced due to change in magnetic flux.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: A
Solution:
As the coil rotates, the magnetic flux linked with the coil (being $ \vec{B}.\vec{A} $ ) will change and emf will be induced in the loop.
