Answer #1

Only magnitude of current would be different.

As induced emf depends on rate of change of magnetic flux.

Rate of change of magnetic flux depend on area and strength of magnetic field.

So induced emf does not depend on metal it depends on size and shape.

But induced current = induced emf/resistance

Here resistance has different value for different metal

So induced current would be different.

Direction of induced emf and induced current would be opposite to changing magnetic flux. It does not depend on metal.
