electricity magnets, and electromagnetism

Electric force

The force of attraction or repulsion

Electric field

The space around a charged object where the force can be found

conductor

Material that allows electricity to flow through it

insulator

Materials that do not let electricity flow

Static electricity

Electric charges built up and at rest

Electric/ Static discharge

The release or jump of static electricity

Electric current

The rate at which electrons flow

Electric currents are measured in

Amps

Voltage

The potential difference between two points that causes Charges to move/flow

Open circuit

The circuit path is not complete and electrons don’t flow

Closed circuit

A complete path where electrons do flow

Three basic parts of a circuit

Energy source what powers the circuit wire the pathway for electrons below what you were trying to make work

Switch

Used to open or close a circuit

Series circuit

The electrons must go through one bulb to get to the next

If one bulb goes out

They all go out

Parallel circuit

Parts are connected so that each load has a separate path

If one bulb goes out

The rest stay on

Fuse

Thin strip of metal that melts in order to open the circuit if it’s too high

Circuit breaker

A switch that opens automatically if the current is too high

Magnet

Any materials that attract iron or materials containing iron

Magnetic pools

The end of the magnets which are the strongest

Magnetic field

The space around the magnet where the magnetic forces can be found

Magnetic force

The force of attraction or a repulsion created by spinning electrons

When you cut a magnet in half you end up with

Two smaller magnets

Temporary magnet

Made for magnetic material and loses its magnetism easily

Temporary magnets can be created by

Lining up domains

Three magnetic metals are

Iron, nickel, and cobalt

Steel is an

Alloy or a man-made metal that is magnetic

Three ways to weaken a magnet is by

Heating it, dropping it and putting it in a strong magnetic field

A compass needle response to a magnetic field because the compass needle is a

Magnet

Electromagnet

A temporary magnet made by using an electric current

Two ways to strengthen electromagnets are

More batteries to increase the electric current and more solenoids to increase the magnetic field

Solenoid

A coil of a wire with an electric current in it
