Lorentz force is an important concept in electromagnetism. When an electric current is flowing in a wire, magnetic field is generated around the wire. Lorentz force acts on a moving charge near the wire. It is known that the Lorentz force can be derived from the Lorentz contraction of electrons and metal ions in the wire. If the charge is stationary with the wire, the Lorentz force is zero on the charge. However, the moving electrons in the wire induce Lorentz force due to the Lorentz contraction of electrons. The purpose of this paper is to experimentally investigate the Lorentz force from the Lorentz contraction of electrons. The Hall element is used to measure the Hall voltage when the control current into the Hall element is zero. The results show that the effect of Lorentz contraction of electrons in the wire is not observed due to thermal effects.
