  1. Magnetism

  2. In this section 1) Magnets 2) Magnetic Domains

  3. Magnets

  4. Magnets A substance which shows magnetic properties Magnets that you may be familiar with - Bar magnets Refrigerator magnets footage.shutterstock.com  lotusoverseas.com Ferrite magnets Horseshoe magnet ed101.bu.edu footage.shutterstock.com 

  5. Magnets magnetic levitation trains (MAGLEV) Magnets that you may not be familiar with- www.gizchina.com

  6. Magnets Regardless of their shape, all magnets have a north pole and a south pole. Like poles repel Unlike poles attract gabyseportifolio.blogspot.com

  7. Magnets NdFeB Magnets Some materials can be made into permanent magnets such as these NdFeB (Neodymium) magnets created in 1982 by General Motors and Sumitomo Special Metals to replace other magnet applications.

  8. Magnets The Iron Triad Recall that rubber and wool can be charged (magnetized) through induction (polarization). Iron can be magnetized, but tends to lose its magnetism over time(soft magnetism). Cobalt and Nickel are difficult to magnetize, but retains their magnetism (hard magnetism)

  9. Magnetic Domains

  10. Magnetic Domains a microscopic region composed of a group of atoms whose magnetic fields are aligned in a common direction. www.magnet.fsu.edu

  11. Magnetic Domains Electron Spin Magnetic field globalspin.com The electron spins of Iron, Cobalt, and Nickel’s magnetic domains are helped by the Earth’s magnetic field to enhance the domains of the Iron Triad. Nonmagnetic domains in materials (woodor plastics) have paired e− spinning in opposite directions to cancel their magnetic properties.
