Yes they are - in both the speaker and microphone.
Electromagnets are temporary magnets made of iron usually that are created by passing a current through a wire wrapped around the iron. There are also ways of making temporary magnets out of ordinary iron objects that can later be demagnetized. I am not wise in the ways of these latter type of temporary magnets.
It makes sense that since some magnets are called "permanent magnets," other magnets should be called "temporary magnets." But since when did English make sense? We usually call them "electromagnets" instead. Electromagnets are used in most electric motors, and cranes that lift scrap metal. They're also used in relays and the write heads of tape recorders (including video tape recorders).
