The question given below consists of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: If a coil is rotated in a magnetic field, an induced emf is produced. Reason:Whenever there is change in magnetic flux linked with a coil, an induced emf is produced.

What is the basic cause of induced e.m.f.?

In a field, the force experienced by a charge depends only upon the magnitude of the field and does not depend upon the velocity. Is field electric or magnetic in nature?

Magnitude of e.m.f. produced in a coil, when a magnet is inserted into it, does not depend upon

Direction. In the following questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : When a coil is moved out of a magnet field acting normally to its plane, induced e.m.f. is produced in it. Reason : The induced e.m.f. is produced in a coil. When it is placed inside the magnetic field
