unlike poles attract A magnet is strongest at the poles A compass needle is a magnet Magnetic materials are composed of many "tiny magnets" called magnetic domains It is possible to magnetize and demagnetize magnetic materials Every magnet is surrounded by a magnetic field An electromagnet is made with a coil of current-carrying wire wrapped around an iron core Magnets are used in motors and generators Lesson Plans Adapted from Operation Primary Physical Science: (OPPS) Magnets Adapted from Mostly Magnets (AIMS) Lesson 1: Introduction to magnets using observation and recording observable properties (working as a member of a cooperative group).
