WebIt is then often convenient to represent the magnetic field intensity in terms of the scalar magnetic potential introduced in Sec. 8.3. From the flux continuity law, (9.2.2), it then follows that satisfies Poisson's equation. A specified magnetization density leads to a prescribed magnetic charge density m. WebIn classical physics, the magnetic field of a dipole is calculated as the limit of either a current loop or a pair of charges as the source shrinks to a point while keeping the magnetic moment m constant. For the current loop, this limit is most easily derived from the vector potential: = =,where μ 0 is the vacuum permeability constant and 4π r 2 is the surface of … WebThus, inside the solenoid the vector potential is ˆ. 2 A = 1 µn r I φφφφ 9.4.1 It is left to the reader to argue that, outside the solenoid (r > a), the magnetic vector potential is ˆ. 2 2 φφφφ r µna I A = 9.4.2 9.5 Divergence Like the magnetic field itself, the lines of magnetic vector potential form closed loops (except in chronic diseases in underserved communities
