Electric Charges
electrically neutral
two types of electric current
direct and alternating
an object that attracts iron and other materials that have magnetic qualities similar to iron
magnet
object has an unbalanced amount of positive or negative charge
electrically charged
a closed or complete path in which an electric current flows
electric circuit
a push or pull a magnetic field applies to either a magnetic material or an electric force
magnetic force
a material in which electrons cannot easily move
electric insulator
machines that transform mechanical energy to electric energy
generator
a region in a magnetic material which the magnetic fields of the atom all point in the same direction
magnetic domain
a material in which electrons can easily move
electric conductor
parts of an electric circuit
electric conductor, energy source, electric device
a temporary magnet made with a current-carrying wire coil wrapped around a magnetic core
electromagnet
the loss of an unbalanced electric charge
electric discharge
the measure of how difficult it is for an electric current to flow in a material
electric resistance
types of material not grouped in magnetic domains
nonmagnetic
