Magnets and magnetism Magnets of similar poles repel each other Magnets of opposite poles attract each other
Magnets and magnetism Materials may be classified as: Ferromagnetic: materials that are strongly attracted to a magnet, Example: Iron, Steel Paramagnetic: materials that are weakly attracted by a magnet Example: aluminum, magnesium Diamagnetic: materials that are non-magnetic, Example: water, wood, plastic
Magnets and magnetism Magnetic materials can be classified as: Hard magnetic materials: These materials retain their magnetic properties after a magnet is removed. Soft magnetic materials: These materials lose their magnetic properties after a magnet is removed.

Magnets and magnetism Magnetic induction: when a magnetic material touches a magnet it also acts as a magnet
Magnets and magnetism Magnetic field lines: are imaginary lines that show: 1. The shape of the magnetic field 2. The strength of the magnetic field 3. Magnetic field lines always move from North -> South repel
Magnets and magnetism Electromagnetism: when an electric current passes through a wire, it induces a magnetic field around the wire (the wire becomes a magnet)
