thermal energy
the internal energy of matter
conduction
when heat is transferred through a solid and occurs when molecules in a substance collide, transferring energy from one molecule to the next
convection
when heat is transferred in liquids and gases; its molecules move farther apart and it becomes less dense
radiation
when heat is transferred through empty space in the forms of rays, waves, or particles and spreads outward from a central source
conductor
a material through which electric current passes easily
insulator
a material through which electric current does not pass easily
poles
a place on a magnet where magnetism is strongest
electromagnetic
a temporary magnet made when an electric current flows through a wire coil
heat
the flow of thermal energy from one place to another
generator
a machine that uses an energy source and magnet to make electricity
