WebCurl of the Electric Field (Digression): 6 . Curl of an electric field is zero. We have shown this for the simplest field, which is the field of a point charge. But it can be shown to be true for any electric field, as long as the field is static. What if the field is dynamic, that is, what if the field changes as a function of time? WebThe second term on the left side is the curl of the curl of the electric field. Now, if E is a central isotropic field, it is of the form E = [xf(r), yf(r), zf(r)] and the x component of the curl of E is . Similarly the y and z components are zero, so the curl of any isotropic central force field (or linear combination of such fields) vanishes.
