Lorentz force plays important roles in electro-magnetic dynamics. It can be derived from Lorentz transformation of electrical fields. Electrical currents in wires are electrons in motion, where metal ions in wires are not moving. The charge density of the electrons in motion changes due to Lorentz contraction. The difference of the charge density between electrons and ions provides an electrical field. This is an origin of Lorentz force. It is pointed out that Lorentz force acts on electrons even if the electrons are not moving in a magnetic field. The Lorentz contraction of electrons in wires is discussed.
