Final answer:
The correct option is b) The movement of a conductor through a stationary magnetic field. Electric current can be induced by magnetism through electromagnetic induction, best demonstrated when a conductor moves through a stationary magnetic field, causing free electrons to form a current.
Step-by-step explanation:
An electric current can be induced from magnetism through the process of electromagnetic induction. This is best exemplified by the scenario where the movement of a conductor through a stationary magnetic field results in an electric current in the conductor. This is due to the fact that a changing magnetic field interacts with the free electrons present in the conductor. The force from the changing magnetic field pushes these free electrons, which form an electric current within the conductor. This principle underlies many devices including electric generators and transformers.
