... In materials such as iron, nickel, and cobalt, groups of atoms are in tiny areas called domains. The north and south poles of the atoms in a domain line up and make a strong magnetic field. If the domains in an object are randomly arranged, the magnetic fields of the individual domains cancel each o ...

... Poisson’s Equation for A Replacing B with ∇ × A in the differential form of Ampère’s Law: ∇ × B = ∇ × ∇ × A = µ0 J Using the identity “curl curl = grad div - delsquared”: ∇2 A − ∇(∇.A) = −µ0 J The choice of ∇.A = 0 is made for static fields This is known as the Coulomb gauge It leads to Poisson’s ...
