Question

Which of the following statements is FALSE?

a) The motional emf caused by a conductor moving perpendicular to a magnetic field induces a current.

b) An induced current is established in a conductor moving through a magnetic field because of the magnetic force on the charge carriers.

c) An induced current is established if there is a changing magnetic field through a loop of wire.

d) An induced current is any current in a circuit that is established by a constant voltage supply, such as a battery.

Explanation / Answer

An induced current is established in a conductor moving through a magnetic field because of the magnetic force on the charge carriers, this is false statement as the current is generated due to changing field, not a constant one
