  3. magnet
  4. magnetic pole
  5. electric generator
  1. a material that attracts iron
  2. b changes mechanical energy (work of machines) to electrical energy
  3. c (1831) discovered that changing magnetic fields (moving magnets) make electrons flow in wires (electricity)
  4. d one of two points such as the ends of a magnet that have opposite magnetic properties
  5. e particles in the outside area of the atom.....when they move and go from atom to atom we call it "electricity"

5 Multiple choice questions

  1. store it with other magnets in a disorderly way - extreme heat - dropping it - hitting it
  2. More loops of wire - More electricity - More metal in the core of the solonoid
  3. magnets made or iron, nickel, cobalt or combinations of these elements
  4. rub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up
  5. a very small building blocks of matter
