What is magnetic field? Surrounds a magnet and exerts a magnetic force on other magnets
What is a simple electric motor? Turns electrical energy into mechanical energy. It contains an electromagnet that rotates between the poles of a magnet.
What do like poles do? Repel
What do unlike poles do? Attract
When an electric current flows through the wire in the electromagnet, a magnetic field is produced, where? In the coils
