Where are Magnetic Poles located? •Every magnet has two ends or sides. Chapter 17: Magnetism and Its Uses. For 50 years, Edward M. Purcells classic textbook has introduced students to the world of electricity and magnetism.

It features hundreds of new examples, problems, and figures, and contains discussions of real-life applications. Section 2: Electricity and Magnetism. The third edition has been brought up to date and is now in SI units. Why are Magnets useful? •Magnets also exert forces on other magnets. B Note CardsAs you read Section 1: Magnetism. Uses of solenoids and electromagnetic devices are discussed, and a description of how these devices work is presented.

Chapter 21Magnetism Section 21.2 Electromagnetism (pages 635–639) This section describes how electricity and magnetism are related. •Magnets can exert forces on objects that are made from, or contain, magnetic materials. chapter Magnetism and Its Uses section Electricity and Magnetism 7 2 What You’ll Learn how an electric current and electromagnet pro-duce magnetic fields about electromagnets and electric motors Highlighting As you read this section, use a highlighter to mark the most important ideas in each paragraph. Magnetic field – the region around a magnet that exerts themagnetic force. He noticed that the flow of the electric current affected the direction the compass needle pointed.
