A form of energy caused by the movement of electrons.
Magnetism
The force of attraction or repulsion of magnetic materials
Atom
Smallest particle of an element
Electron
Negatively charged, subatomic particle
Electric Field
The space around a charged object in which another charged object experiences an electric force
Conductor
A material that allows electrons to move easily through it.
Insulator
A material that does not allow heat or electrons to move through it easily.
Induction
A transfer of charge without contact between materials
Electric Current
The continuous flow of electric charges through a material
Grounding
The transfer of excess charge through a conductor to Earth
Resistance
A material’s opposition to the flow of electric current.
Magnetic Field
A region around a magnetic material or a moving electric charge within which the force of magnetism acts.
Generator
A machine that converts mechanical energy into electrical energy
Electromagnetism
The relationship between electricity and magnetism is called
