SC.3.P. PHYSICAL SCIENCE: ENERGY TRANSFER-ELECTRICITY AND MAGNETISM
3.P.3. The student will demonstrate an understanding of how electricity transfers energy and how magnetism can result from electricity.
3.P.3B. Conceptual Understanding: 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.
Students who demonstrate this understanding can:
3.P.3B.1. Develop and use models to describe and compare the properties of magnets and electromagnets (including polarity, attraction, repulsion, and strength).
