1 Electrons-Subatomic particle that has almost no weight and carries a negative charge; orbits in a shell about the nucleus of an atom. 2  Neutrons-Subatomic particle that has a weight of one atomic mass unit, carries no charge, and is found in the nucleus of an atom.
Using the right hand and pointing the thumb in the direction of the moving positive charge or positive current and the fingers in the direction of the magnetic field the resulting force on the charge points outwards from the palm. The force on a negatively charged particle is in the opposite direction.
