Abstract: The historical development for the concept of magnetic monopole is briefly described. According to Lorentz transformation, the relativistic covariant of electromagnetic field tensor and 4 - dimension forces, and the relativistic invariance of electric charge, it can be directly proved that a moving magnetic monopole will be actedby a magnetic Lorentz force, and that the magnetic Lorentz force has the same accuracy as the Coulomb low. Dirac quantization condition of electric charge is derived with magnetic Lorentz forces. Finally, an experimental scheme to test and verify the magnetic Lorentz force is suggested.
