Question 1: Electromagnetic Induction

Question

Assertion : A metallic surface is moved in
and out in magnetic field then emf is
induced in it.
Reason : Eddy current will be produced in a
metallic surface moving in and out of
magnetic field.

Accepted Answer

When a metallic surface is moved in and out
in magnetic field, then magnetic flux linked with
metallic surface is changed continuously, hence
according to FaradayÃ¢ÂÂs law of electromagnetic induction, an induced emf is produced. Since,
metallic plate behaves as closed path, therefore an
induced current (eddy current) starts flowing in
the metallic surface. Hence, assertion and reason
both are true and reason is the correct
explanation of assertion.

Answer

If both assertion and reason are true and reason
is the correct explanation of assertion.

Answer

If both assertion and reason are true, but reason
is not the correct explanation of assertion.

Answer

If assertion is true, but reason is false.

Answer

If both assertion and reason are false.

Electromagnetic Induction

Assertion : A metallic surface is moved in and out in magnetic field then emf is induced in it. Reason : Eddy current will be produced in a metallic surface moving in and out of magnetic field.
