8th Grade Ch. 1 Sec. 2 Inside a Magnet

  1. 1. Ch. 1 Sec. 2 Inside a Magnet
  2. 2. atom smallest particle of an element that has properties of that element
  3. 3. parts of an atom central core of atom positive charge negative charge- creates magnetism no electric charge
  4. 4. element 1 of about 100 basic materials that make up matter
  5. 5. magnetic domain cluster of billions of atoms that all have magnetic fields lined up in same way in magnetized material all or most of domains - arranged in same direction
  6. 6. ferromagnetic material material that shows strong magnetic effects common examples: iron, nickel, cobalt
  7. 7. Making Magnets made from ferromagnetic material temporary magnet = easy to magnetize - loses magnetism quickly permanent magnet = keeps its magnetism
  8. 8. Making a temporary magnet I predict that my temporary magnet (aka the nail) will pick up ________ paper clips.
  9. 9. causes magnetic domains to become randomly arranged ways to destroy a magnet drop it strike it hard heat it
  10. 10. Review Time
  11. 11. atom smallest particle of an element that has properties of that element
  12. 12. parts of an atom central core of atom positive charge negative charge- creates magnetism no electric charge
