Question

1.When the current in a coil varies an emf is generated.

2.The energy of a magnetic field depends on the conductor in the field.

3.The maximum current that flows in an inductor connected across the terminals of a battery is limited by the internal resistance of the battery and the finite resistance of the coil of wire from which the inductor is made.

4.A conductor is required for a changing magnetic field to produce an electric field.

5.An inductor, in which the electric current is changing, generates an emf whose sign would create a current that, if it flowed, would oppose the change in magnetic field creating the emf.
