Explaining Magnetism by Relativity

Authors: Nabin Timalsina

In this paper , equations of Magnetism are rediscovered by using Special Relativity and Coulomb's law with different method and various cases are studied . Magnetic field near a current carrying conductor is redefined as ratio of relativistic electric field experienced by reference frame of a moving charge near the conductor to velocity of that reference frame with respect to the conductor. Mathematically, it is found that the existing formulas of magnetism given by Biot- Savart Law are valid only for normal velocities and completely fail for higher or microscopic velocities of moving charge. 'Fleming's Right/Left Hand Rules' can easily be explained by Relativity as just interaction between charges. Unlike existing idea, a magnet or current carrying conductor can exert some force even on charges at rest. Magnetic field due to a current carrying conductor is nothing but ratio of approximate relativistic electric field to the velocity of reference frame. Lorentz force can be calculated as 'Just Electric Force' rather as 'Sum of Electric and Magnetic Force' by using Relativity. Magnetic force is just an electric force in Relativistic Electrodynamics that could not be explained by Classical Electrodynamics. The values of speed of light in vacuum and permittivity of free space are fundamental and permeability depends upon them given by formula µ = 1/εc^2. It is claimed that "As Maxwell's Equations are based upon existing equations of Magnetism which are only approximation for lower velocities and fail in higher velocities, they are likely to be useless now". It is suggested that, "As Magnetic Force is nothing but Electric Force in Relativistic Electrodynamics, the name of one of the four fundamental forces ; 'Electromagnetic Force' should be changed into just 'Electric Force'." It is claimed that radiations are just non-mechanical waves that can propagate at velocity of light and are not necessarily electromagnetic in nature. Moreover, the writer suggests that electromagnetic waves may not exist at all.
