If a permanent magnet picks up a steel paper clip, the paper clip also becomes a magnet. How does an electromagnet differ from the magnetized
paper clip?
A. An interaction between electricity and magnetism produces an
electromagnet, while a permanent magnet induces the paper clip's
magnetic field.
B. A magnet does not form when an electric current interacts with a
magnetic field, but a magnet will form when an electromagnet
interacts with a permanent magnet.
C. An interaction between electricity and magnetism induces the
paper clip's magnetic field, while an electromagnet is produced by
a permanent magnet.
D. An electric current can run through a permanent magnet to
magnetize the steel paper clip, but an electric current cannot run
through the paper clip.
