Develop and use models to describe and compare the properties of magnets and electromagnets (including polarity, attraction, repulsion, and strength).
- Physical Science: Energy Transfer - Electricity and Magnetism
The student will demonstrate an understanding of how electricity transfers energy and how magnetism can result from electricity.
Magnets can exert forces on other magnets or magnetizable materials causing energy transfer between them, even when the objects are not touching. An electromagnet is produced when an electric current passes through a coil of wire wrapped around an iron core. Magnets and electromagnets have unique properties.
