Assertion : A metallic surface is moved in and out in a magnetic freld, then emf is induced in it.
\( \mathrm{P} \)
Reason : Eddy current will be produced in a metallic
W surface moving in and out of magnetic field.
(a) Both assertion and reason are true and reason is the correct explanation of assertion.
(b) Both assertion and reason are true but reason is not the correct explanation of assertion.
(c) Assertion is true but reason is false.
(d) Both assertion and reason are false.
