IMPORTANT DEFINITIONS:
Click here --> Definitions of electricity and Magnetism
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 beswitch 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.
