Document Summary
The magnitude of charge of the electron or proton is a natural unit of charge. Induction- a charge of the opposite sign is given without losing its own charge: conservation of energy- the sum of all electric charges in any closed system is constant, for point charges, coulombs law says that: e=1/r2. Electric field as electric force per unit charge e=f0/q0. Principle of superposition of electric fields e=f0/q0=e1+e2+e3+ : lambda- linear charge density, sigma- surface charge density, rho- volume charge density. When electric and magnetic fields are opposite on a charge q, the electric and magnetic fields must be perpendicular.
