  1. magnetic force
  2. types of turbines
  3. Michael Faraday
  4. electromagnetism
  5. Hans Christian Oersted
  1. a interaction of electricity and magnetism
  2. b (1831) discovered that changing magnetic fields (moving magnets) make electrons flow in wires (electricity)
  3. c wind - water - geothermal - nuclear ----- all of them turn to generate electricity by passing magnets by wires to move electrons
  4. d (1820) discovered that moving charges (electricity) can create magnetic fields
  5. e the force of attraction or repulsion created by moving or spinning electric charges

5 Multiple choice questions

  1. particles in the outside area of the atom.....when they move and go from atom to atom we call it "electricity"
  2. material that attracts iron
  3. rub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up
  4. the area of the earth with moving iron that creates our magnetic field...not every planet has this
  5. creating electrical current by moving a magnetic field past a coil of wires

5 True/False questions

  1. electric generatorchanges electrical energy to mechanical energy (it can do work)


  2. temporary magnetseasy to magnetize, but don't stay magnetized for long


  3. north geographic pole ("top" of the Earth)store it with other magnets in a disorderly way - extreme heat - dropping it - hitting it


  4. electric motorchanges electrical energy to mechanical energy (it can do work)


  5. domainsmaterial that attracts iron
