Find out how relationships between magnets and electricity were discovered and how they are explained by the Electromagnetic Theory. Learn about a motor, a device that has the ability to convert electrical energy into mechanical energy. Also learn about another device – a generator that is used when mechanical energy is transferred into electrical energy. Discover what electromagnets are and how they work. Includes photographs, animations, and experiments. There is a link to an eThemes resource on magnets.
Learn about the basics of magnetism - what is it, what is a magnetic field, how can we measure magnetism, what is an electromagnet, the theory of electromagnetism, what use are magnets, which materials are magnetic, how different materials react to magnetism, what causes magnetism, and a brief history of magnetism.
This video demonstrates how electromagnetism can be used to create a simple motor. (Total Running Time: 2:05)
