Electric Current

Electrons are pushed from atom to atom

Electrons have negative charge

Electric Circuit

A series circuit with only one path for current to flow through.

Parallel circuits have an advantage over series circuit.

The second bulb will still glow after the first bulb goes out.

Magnetic Fields

Space around a magnet in which it can affect other magnets.

Magnetic domain

Is made up of a large number of atoms whose magnetic fields point in the same direction.

Earth acts like a giant magnet. It has a magnetic field this is what causes all compasses to point north.

Electric Motor

Is made of an electromagnet, a permanent magnet, and an object that changes the direction of the electric current. An electric motor changes electrical energy to kinetic energy.

Magnetism and Electricity

Magnetic fields can also be used to make electric current in a wire.

Generator

Changes mechanical energy into electrical energy.

They are made of a permanent magnet and a coil of wire.

The coil must spin in order to produce an electric current
