  • a material that does not allow electrons to move through it easily
    insulator
  • What makes something magnetic
    it has groups of atoms with aligned magnetic poles
  • the net movement of electric charges in a single direction
    electric current
  • Opposite charges _______
    attract
  • a circuit with only on path
    series
  • give an example of an insulator
    plastic, glass, wood
  • like charges (+/+ or -/-) __________
    repel
  • a closed path that current follows
    circuit
  • the tendency for a material to resist the flow of electrons
    resistance
  • Add this to your circuit to slow the flow of current
    resistance
  • explain how you magnetized the paper clip in last weeks lab. Be very specific about how it became magneticf
    rubbing the paper clip along the magnet aligned its atoms creating magnetic domains
  • a material that allows electrons to move through it easily
    conductor
  • Draw the magnetic field lines around a magnet
    see board
  • The accumulation of excess charge on an object
    static electricity
  • surrounds every charge and exerts a force that causes other charges to be attracted or repelled
    electric field
  • the north and south poles of two magnetics will _____
    attract
  • the unit used to measure current
    amps
