| 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 acted- by a magnetic Lorentz force,and that the magnetic Lorentz force has the same accuracy as the Coulomb low.Di- rac 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. |
