The value of the constant of proportionality denoted by beta is currently unknown to me, which is why experimentation is so important.

You may object because the curl of a gradient is said to always be zero. But that is only true for simply connected regions.
If there is a singularity at the center, then there can be a nonzero curl around the center even though everywhere else, the curl of the gradient is indeed zero.
