Chapter 16. Act(10) Make a electromagnet

Chapter 16. Act(10) Make a electromagnet. An electromagnet is a type of magnet in which the magnetic field is induced by the flow of an electric current through a coil of wire. The strength of the electromagnet depends on the amount of electric current and the number of turns of the coil.
