Magnets

Magnets attract certain metals. They have two poles that attract or repel the poles of other magnets. Lines of force form a powerful magnetic field around a magnet. Magnets come in many shapes and sizes, and are used for many purposes. Without magnets, our lives would be quite different. They help generate electricity, are used in motors, and can be found in a variety of common items. Magnets are used in medicine, industry, transportation, and in other important fields. In this unit, students will learn that magnets behave in predictable ways, making them reliable and valuable tools.
