ELECTRICITY

​Electricity refers to the build-up or movement of charges. Natural processes can lead to the build-up of charges (static electricity) between materials. Humans have developed technologies to harness the flow of charges (electric current) to transfer energy locally and over long distances.

any type of object through which an electric current can flow.

INSULATORS

any type of object through which an electric current CANNOT flow.

Insulator Examples:

Glass

Plastic

Rubber

Leather

ELECTRIC CURRENT

Energy can be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light.

Electricity in circuits can be transformed into light, heat, sound, and magnetic effects. Electrical circuits require a power source and a complete loop through which an electrical current can pass.

MAGNETISM

Electricity and magnetism are interconnected forms of energy, and each can produce the other. Electric currents produce magnetics fields and the movement of magnets can produce electric current in a conductor.

ELECTROMAGNET

Certain metal objects can produce a permanent magnetic field that attracts or repels other magnets and attracts iron-containing metal objects. Temporary electromagnets can be produced by running electric current through a coil of wire wrapped around iron-containing metal core.

In general, the wire in an electromagnet is wrapped around a core made of a magnetic metal, such as iron or steel. A magnetic field is created around the wire, turning the core into a temporary magnet.

When the electric current is turned off, the magnetic field quickly fades. You can make an electromagnet using a circuit with a battery, and a wire wrapped around a nail.
