5 Matching questions

  1. ferromagnets
  2. electrons
  3. electromagnetism
  4. electromagnet
  5. electromagnetic induction
  1. a magnets made or iron, nickel, cobalt or combinations of these elements
  2. b interaction of electricity and magnetism
  3. c a solenoid with a iron core...strong magnetic field
  4. d creating electrical current by moving a magnetic field past a coil of wires
  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. wind - water - geothermal - nuclear ----- all of them turn to generate electricity by passing magnets by wires to move electrons
  2. easy to magnetize, but don't stay magnetized for long
  3. the force of attraction or repulsion created by moving or spinning electric charges
  4. (1820) discovered that moving charges (electricity) can create magnetic fields
  5. difficult to magnetize, but remain magnetized for longer amounts of time

5 True/False questions

  1. Michael Faraday(1831) discovered that changing magnetic fields (moving magnets) make electrons flow in wires (electricity)

          

  2. how to "mess up" a magnetrub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up

          

  3. how to create a magnetrub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up

          

  4. solenoidsmall sections of atoms that are lined up to make a magnetic field

          

  5. electric generatorchanges mechanical energy (work of machines) to electrical energy
