Magnetic Potential The magnetic potential at any point in the magnetic field is measured by the work done in moving a unit Npole (i.e. 1 Wb strength) from infinity to that point against the magnetic force. Consider a magnetic pole of strength m webers placed in a medium of relative permeability μ _{r}.At a point at a distance x metres from it, the force on unit Npole is
If the unit Npole is moved towards m through a small distance dx, then work done is
The negative sign is taken because dx is considered in the negative direction of x. Therefore, the total work done (W) in bringing a unit Npole from infinity to any point which is d metres from m is
The negative sign is taken because dx is considered in the negative direction of x. Therefore, the total work done (W) in bringing a unit Npole from infinity to any point which is d metres from m is
By definition, W = Magnetic potential V at that point. Note that magnetic potential is a scalar quantity.
