Magnetism & Electricity Vocabulary List & Definitions
current
the flow of electricity in a conductor.
electricity
a physical phenomenon caused by the movement of
certain charged particles such as electrons, esp. between
points having different electrical charges, and seen in
naturally occurring phenomena such as lightning and
magnetic attraction and repulsion.
electromagnet
a magnet in which an iron or steel core is magnetized by
the electric current in the coil of insulated wire wound
around it.
electron
a negatively charged particle, considered a fundamental
unit of matter, that exists independently or outside the
nucleus of an atom.
force
active power, energy, or physical strength.
lodestone
a rock that possesses magnetic properties and attracts
iron; magnetite.
magnet
an object that attracts iron and some other materials by
virtue of a natural or induced force field surrounding it.
attract
to cause to come near, as by some special quality or
action.
battery
a device that generates electricity by means of chemical
reactions.
repel
to drive away or force backwards.
circuit
an arrangement of electronic elements, including
conductors, resistors, and the like, through which electric
current moves.
