Answer

Answer:

A. It doesn't function without a source of current.

Brief Explanations:

An electromagnet works due to electric - current induced magnetism. Without current, there is no magnetic field. Its core is usually made of a ferromagnetic (magnetic) material. It creates a magnetic field using electric current, not moving magnets to create an electric field, and it is not a permanent magnet.
