1. Inside a Magnet Chapter 1 Section 2 Pages 14 - 19

2. Objective: Explain how the alignment and misalignment of magnetic domains affect magnetism. Atom: The smallest particle of an element Element: One of about 100 basic substances that make up all matter. Draw and atom here: Structure of an atom: *Nucleus: The center region of an atom *Proton: A particle that carries a positive charge *Neutron: A particle that does not carry a charge *Electron: A particle that carries a negative charge

3. A spinning electron produces a magnetic field that makes the electron behave like a tiny magnet in an atom. Magnetic Domains: A grouping of atoms that have their magnetic fields aligned. Unmagnetized MaterialMagnetized Material In a magnetized material, all or most of the magnetic domains are arranged in the same direction.

4. Ferromagnetic Material: material that shows strong magnetic properties. *Examples: IRON, NICKEL, COBALT, & ALNICO Temporary Magnet: A magnet made from a material that easily loses its magnetism. Permanent Magnet: A magnet made from a material that keeps its magnetism for a long time. One way to destroy a magnet is to drop it or strike it hard. If it is hit hard, its domains can be knocked out of alignment.
