Unit 3 - Electromagnetism

Front 1

Magnetism

Back 1

The force of attraction or repulsion of magnetic materials

Front 2

Magnetic Field

Back 2

Area surrounding a magnet that applies a force (a push or pull) without actually touching an object

Front 3

Magnetic Materials

Back 3

A material made of iron, nickel, or cobalt that is attracted to a magnetic field

Front 4

Electric Current

Back 4

The flow of electrical energy

Front 5

Electromagnetism

Back 5

The interaction of electric currents and magnetic fields; electric currents can be used to create magnetic fields and magnetic fields can be used to create electricity

Front 6

Electromagnet

Back 6

Temporary magnet created by wrapping a current carrying wire around an iron core

Front 7

Electric Motor

Back 7

Device that transforms electrical energy into mechanical energy

Front 8

Generator

Back 8

Device that uses a magnetic field to turn mechanical energy into electrical energy

Front 9

Turbine

Back 9

Huge wheels or fan blades that rotate when pushed by water, wind, or steam; are used to spin generators at power plants to make electricity

Front 10

Electric Circuit

Back 10

A complete, unbroken path through which electricity flows

Front 11

Conductor

Back 11

An object or type of material that allows the flow of electrical or thermal energy

Front 12

Transformer

Back 12

An object that changes electrical energy into another form of energy, for example a buzzer or light bulb

Front 13

Buzzer

Back 13

A transformer that changes electrical energy into sound energy

Front 14

Light bulb

Back 14

A transformer that changes electrical energy into radiant energy

Front 15

Closed Circuit

Back 15

A circuit with a complete path that allows electricity to flow to the transformer to change electrical energy into another type of energy

Front 16

Open Circuit

Back 16

A circuit with an incomplete path that does not allow electricity to flow to the transformer

Front 17

Battery

Back 17

Changes stored chemical energy into electrical energy when hooked up to a circuit; used as a source of electricity

Front 18

Solar Cell

Back 18

Changes solar energy from the sun into electrical energy; used as a source of electricity

Front 19

Switch

Back 19

A device used to open and close a circuit
