The production of a magnetic field around an electrical current is called electromagnetism. The placement of an electric current in a preexisting magnetic field can cause motion. When this happens, electrical energy is transformed into mechanical energy. The use of electrical energy to produce mechanical energy is the principle behind the workings of an electric motor.

The resources above cover the following skills:
Physics: Students will use scientific skills and processes to explain the interactions of matter and energy and the energy transformations that occur
Electricity and Magnetism: Cite evidence supporting that electrical energy can be produced from a variety of energy sources and can itself be transformed into almost any other form of energy.
Research and identify various energy sources and the energy transforming devices used to produce electrical energy: Wind (generators, wind mills); Sun (solar cells); Water (turbines); Fossil fuels (engines).
Cite examples that demonstrate the transformation of electrical energy into other forms of energy.
Electricity and Magnetism: Identify and describe magnetic fields and their relationship to electric current.
Describe how the electromagnet demonstrates the relationship of magnetism and electricity and identify common devices that demonstrate application of this relationship: Electric motors (fans, hair dryers, can openers); Electrical generators (turbine).
