Indicate true or false in each of the following statements:
True False A free electron in a magnetic field will not move when the magnetic field changes.
True False Current never flows at the instant a coil is connected to a battery.
True False The energy of a magnetic field is proportional to the square of the rate of change of field.
True False An inductor, in which the electric current is changing, generates an emf whose sign would create a current that, if it flowed, would support the change in magnetic field creating the emf.
True False An emf is generated in a coil when the current is switched on.
