- Electricity is the presence or motion of charged
particles.
- Elctricity can be static or dynamic based on whether the
elctrons are static or in motion.
- Static electricity is the build up of charges on the surface or
in the bulk of an object
- Like charges repel each other and unlike charges attract each
other
- Motion of electrons gives rise to current or dynamic
electricity
- Based on the ability of an object to allow motion of electrons,
they can be classified into conductor, semiconductor or
insulator.
- Moving charges or current gives rise to magnetic force or
magnetism
- Magnetic force can interact with other magnetic material from a
distance
- Magnetic field is the region around a magnet where the effect
of magnetism can be fel
From the above we can see that electricity and magnetism are
interlinked.
