Electric current: is the flow of electric charge through a conductor. 

Electric circuit: it is a continuous conducting path that electric current can

flow along.

An electron: is a particle of an atom that is negatively charged and orbits

around the nucleus of the atom.

Electron (-)

Proton (+)

Neutron

Magnetic bar: it’s a permanent magnet because it can’t be

switch on and off. It always has a magnetic field. The lines

around it represent the magnetic field.

Magnetism: is an invisible force between two magnetic objects or between a magnetic object and an object made of magnetic materials (for example, iron).

Magnetosphere: is the Earth's magnetic field. The magnetosphere 

protects life on Earth by deflecting solar radiation.

The center of the Earth is made up of liquid iron, due to the rotation of the Earth liquid iron moves and produces a magnetic field around it.

Compass: it’s an instrument that detects the Earth’s

magnetic field and helps us to find our way.
