Note that this equation gives a forcefw which is always in the radial direction.The other two equations considered today incorporate the Neumann'®idea of a vector potential. The electric field strength H is defined in terms ofboth a scalar potential (p and a vector potential A by the equationdAE « -grad (pdt(4)while the magnetic flux density B is expressed in terms of the vectorpotential A asB - curl A .(5)
