The observations of electrical and magnetic phenomena probably go back as far as the existence of humans. The static shock you ... are all aspects of electric and magnetic forces. As you have already learned, these forces are considered fundamental, i.e. they are not due to some other underlying force as far as we know.

Electromagnets are found in motors, tape decks, hard drives, VCRs and tons of other devices. Find out what makes an electromagnet "electro" and learn how to make one at home. ... The basic idea behind an electromagnet is extremely simple: By running electric current through a wire, you can create a magnetic field.
