5 Matching questions

  1. magnetic force
  2. magnetic pole
  3. electric motor
  4. aurora
  5. Michael Faraday
  1. a (1831) discovered that changing magnetic fields (moving magnets) make electrons flow in wires (electricity)
  2. b changes electrical energy to mechanical energy (it can do work)
  3. c the force of attraction or repulsion created by moving or spinning electric charges
  4. d a curtain of lights which result from solar wind burning up in the atmosphere at the poles
  5. e one of two points such as the ends of a magnet that have opposite magnetic properties

5 Multiple choice questions

  1. a coil of wire with an electric current running through it...creates a magnetic field
  2. rub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up
  3. a solenoid with a iron core...strong magnetic field
  4. particles in the outside area of the atom.....when they move and go from atom to atom we call it "electricity"
  5. small sections of atoms that are lined up to make a magnetic field
