How to calculate divergence of a vector
WebThe vector (-y, x) points in the direction and has 0 divergence already. It can be written as The direction is normal to both of these and you can get a vector in it by taking the cross product of (-y, x, 0) and (x, y, z), with result (xz, yz, -r 2 ). This vector has divergence 2z, and the form rz ur - r 2uz. Web25 nov. 2015 · Let us understand this conceptually. We have ∇ ⋅ B = 0, therefore we require a vector function A such that B = ∇ × A so that its divergence vanishes. As ∇ × B = μ 0 J, we can write ∇ ( ∇ ⋅ A) − ∇ 2 A = μ 0 J. Now, it is possible to choose A such that its curl remains unaltered but its divergence vanishes.
