What happens when a magnetic field changes? a. It forms a scalar field. b. It remains constant C. It generates an electric field d. It dissipates into space.

The correct answer is C. It generates an electric field.When a magnetic field changes, it induces an electric field. This phenomenon is known as electromagnetic induction. The changing magnetic field creates a force that drives the flow of electric charges, resulting in the generation of an electric field. This principle is the basis for the operation of generators, transformers, and many other electrical devices.
