Electricity & Magnetism

when matter has an overall positive or negative charge

• neutral

• electric charge

• repel

• insulator

when the positive & negative charges are the same

• attracts

• repel

• neutral

• conductor

when objects push away - both have the same charge

• attract

• static

• neutral

• repel

when objects pull toward each other - opposite charges

• neutral

• repel

• attract

• static

the push or pull of charged objects on each other

• electric force

• insulator

• discharge

• static

a place where electrical charges can move easily

• repels

• neutral

• conductors

• insulators

transfer of particles with an electric charge between objects not touching

• static discharge

• electric charge

the cause of the force

• magnets

• source

• interact

the Earth is an example of this

• repelling

• natural magnet

when magnetism can't be turned off or on

• electromagnets

• permanent magnets
