Amps
Measurement of electric current
Atom
A neutral partical (everything is made from aroms)
Attract
opposite poles of a magnet attract and positive and negative charges attract.
Battery
Two or more electrical cells joined together
Cell
A chemical store in energy which gives power to cherge around the circuit
Conductor
A material that conducts energy well
Core
A rod of a material placed inside a coil to make a electromagnet stronger
Current
The flow of electrical charge (electrons) around a complete circuit per second
Electronic charge
A property of a material or particle that can be positive or negative
Electrical field
A region where a charged material or particle experiences a force
Electromagnet
A temporary magnet produced using an electric current
Electron
A negatively charged particle found in atoms. Electrons flow through a wire when a current flows
Insulator
A material that doesn’t conduct energy well
Lightning
A current through the air that produces light and sound
Magnetic field
A region where there is a force on a magnet or magnetic material
Magnetic field lines
Imaginary lines that show the direction of the force on magnetic material
Magnetic material
A material attrckred to a magnet
Magnetise
Make into a magnet
Motor
A machine or component that spins When a current flows through it
Negative
The charge on an electron Or an object that had had electrons through it
Neutral
Describes an object or particle that has no charge, or in which positive and negative charges cancel out, giving no charge overall.
Neutron
A neutral particle found in atoms
