Magnetic Charge, Magnetic Current, Lorentz Magnetic Force, Lorentz Electric Force
The Lorentz force on a charged particle in the presence of a magnetic field has long been known, and Lorentz electric force on an electrical charge is a common phenomenon. Since the formulation of magnetic charge, Lorentz magnetic force on a magnetic charge has not been given. Here, we give the resultant magnetic force on a magnetic charge that causes the magnetic charge to move in or trace a circular path in the right hand grip rule for a straight wire carrying an electrical current, explaining why magnetic field lines are circular and why they form closed loops even in solenoids, and comparison is made with the resultant Lorentz electrical force that causes an electric charge to move in a circular path in the presence of a magnetic field. The weight of magnetic charge is seen to be equal to that of electric charge.
