How eddy currents can be produced?

Assertion : If a varying current is flowing through a machine of iron, eddy currents are produced. Reason : change in the magnetic flux thro' an area causes eddy currents.

Assertion: Eddy current is produced in any metallic conductor when magnetic flux is changed aroundn it. Reason: Electric potential determines the flow of charges

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.
