5 Matching questions

  1. solenoid
  2. types of magnets
  3. electric motor
  4. permanent magnets
  5. domains
  1. a ferromagnets, electromagnets, permanent, temporary
  2. b changes electrical energy to mechanical energy (it can do work)
  3. c difficult to magnetize, but remain magnetized for longer amounts of time
  4. d a coil of wire with an electric current running through it...creates a magnetic field
  5. e small sections of atoms that are lined up to make a magnetic field

5 Multiple choice questions

  1. one of two points such as the ends of a magnet that have opposite magnetic properties
  2. interaction of electricity and magnetism
  3. changes mechanical energy (work of machines) to electrical energy
  4. More loops of wire - More electricity - More metal in the core of the solonoid
  5. particles in the outside area of the atom.....when they move and go from atom to atom we call it "electricity"

5 True/False questions

  1. electromagnetic inductioncreating electrical current by moving a magnetic field past a coil of wires


  2. ferromagnetsa solenoid with a iron core...strong magnetic field


  3. magnetic forcethe force of attraction or repulsion created by moving or spinning electric charges


  4. how to "mess up" a magnetstore it with other magnets in a disorderly way - extreme heat - dropping it - hitting it


  5. Earth's corethe area of the earth with moving iron that creates our magnetic field...not every planet has this
