Magnetism Attractive and Repulsive What Is A Magnet? •Magnet: any object that attracts iron or materials containing iron 1. Two poles 2. Exert forces 3. Surrounded by a magnetic field Magnetic Poles • Every magnet has two poles The parts of a magnet where the magnetic effects are the greatest Magnetic Forces • The force of repulsion or attraction between the poles of magnets Magnetic Fields • Exist in the region around a magnet in which magnetic forces can act Simulated Magnetic Field Drawing Actual Iron Filling Behavior Half a Magnet? • What happens if you cut a magnet into pieces? Electromagnetism • The interaction between electricity and magnetism Solenoids • A coil of wire that produces a magnetic field when carrying an electric current Electromagnets • Magnet that contains a solenoid wrapped around an iron core Hundreds of times stronger due to the combined magnetism of the solenoid and the iron core
