Plot Magnetic field normal component along a line over a surface
I kindly ask if is possible, with the aid of the Fields Calculator, define a Named Expressions able to plot the normal component of the magnetic field over a surface (this will generate a scalar value on a surface SclSrf) and then evaluate these scalar value only alog a definited circular path that is on this surface.
I think about this approach in order to use it to evaluate the normal component of the field along a circular curve that is parallel to the XY global plane at a fixed z coordinate. The tangential components over a circular path is easy to evaluate by using the Tangent, but for the Normal it require a surface so may be an approach (if is possible) calculate the normal scalar value over a surface that intersect the curve and then extract only the values on this curve, may be a possible/valid approach? There are other approach?
