WebMaxwell's equations, there are four equations in the set of Maxwell's equations and most of them don't carry Maxwell's name. That is a quirky feature. That one tells you about the curl of the electric field. Now, depending on your knowledge, you might start telling me that the curl of the electric field has to be zero because it is the gradient Webc = curl (V,X) returns the curl of symbolic vector field V with respect to vector X in three-dimensional Cartesian coordinates. Both the vector field V and the vector X must be vectors with three components. c = curl (V) returns the curl of the vector field V with respect to a default vector constructed from the symbolic variables in V.

"WebFeb 12, 2024 · The usual definition that I know from tensor calculus for the Curl is as follows. (2) curl T := ∑ k = 1 3 e k × ∂ T ∂ x k. However, it turns out that Mathematica's definition for curl is totally different. For example, it returns the Curl of a second order tensor as a scalar, while according to ( 2) it should be a second order tensor. " - Curl equation
