Unit 4 Vocab

the flow of electrons through a wire or any conductor; measured in amperes with an ammeter

• current

• motor

• electric field

• electricty

an electrical current also known as a flow of electrons passing through

• motor

• electrical charge

• induction

• volt

electrically charging an object or creating an electrical current in it, without physically touching it

• induction

• gravitational field

• electric field

• insulator

a material that does not allow heat or electricity to move through it easily

• conductor

• motor

• volt

• insulator

states that like charges repel or push away, and opposite charges attract

• magnetic force

• magnetic poles

• electricity

• law of electric charges

the region around a magnet where magnetic forces act

• motor

• magnetic field

• generator

• induction

involves the simultaneous attraction and repulsion that occurs between parties that are electrically charged and are within a magnetic field

• motor

• magnetic force

• conductor

• circuit

the two ends of a piece of magnetic material where the magnetic forces are strongest, labelled north and south pole

• current

• electrical charge

• magnetic force

• magnetic poles

a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts

• volt

• motor

• electromagnet

• series circuit

an electrical circuit where the current flows through more than one path; if one path is interrupted, current will still flow through the other paths

• parallel circuit

• magnetism
