| Abstract: | This paper discusses additional magnetic field created by the charge on the conductor which moves in the uniform steady magnetic field (external magnetic field). It has been concluded by calculation that the additional magnetic field is much smaller than the external field and it can be ignored properly when we calculate the motional E. M. F. |
