parallelcircuit		Groups of atoms with aligned magnetic poles
electricfield		The region around a magnet where magnetic forces act
magneticfield		AC
current		This is expressed in watts (W) or kilowatts (kW)
insulator		The opposition to the flow of electrons through a conductor
electromagneticinduction		Increases or decreases the voltage of an alternating current
voltmeter		An electrical circuit where the current flows through more than one path
superconductor		V = I x R
directcurrent		A power source that acts as an electron pump; "dry" because it uses a thick, pasty electrolyte
electricmotor		A power source that acts as an electron pump; "wet" because it uses a liquid electrolyte
circuit		Changes elecrical energy to magnetical energy
magneticpoles		A device used to detect the presence of electric charges
electromagnet		The two ends of a magnet
magnetism		Creating an electrical current by passing a wire through a magnetic field
staticelectricity		An area surrounding an electron that exerts a force on anything nearby with an electric charge
electroscope		It equals 1000 watts
magneticdomain		Measures potential differences
alternatingcurrent		A material that does not allow heat or electrons to move through it easily
ammeter		A closed circuit through which electrons flow
resistance		The build-up of electrical charges on an object
kilowatthour		DC
electricalpower		A galvanometer that measures electrical current passing through in amperes
drycell		A material that allows electrons to move easily through it
generator		An electrical circuit where the current has only one path.
conductor		Magnet made by wrapping a wire coil around an iron core
seriescircuit		Has no electrical resistance; current does not loose energy
transformer		The flow of electrons through a wire or any conductor
wetcell		Induces electrical curent by rotating loops of wire through a magnetic field
potentialdifference		Force of attraction between unlike poles or repulsion between like poles
ohmslaw		This is measured in volts (V)
