Procedure

Permanent magnets are always magnetic.
There is another way to make a magnet, using electricity.
Make electromagnets.
Make or demonstrate a hand-wound motor, to show that it works by an electromagnet.
Optional: make a speaker.

Electromagnets are used constantly in our lives, as motors, speakers, door bells, maglev trains, moving large pieces of metal around e.g. scrap metal yards, MRI machines.
