| Here is for example the magnetic scalar field: (* Get the "magnetic scalar potential" *) rbm = Entity["PhysicalSystem", "RectangularBarMagnet"][ "MagneticScalarPotential"]; (* Make "magnetic scalar potential" `Active` and replace... |
| Hi, I have `n` number different `3D` vector fields which are partially overlaying on each-other, but not at the same mesh points. Let's say `n=2` and ... |
| Yes, I know. These are some Mesh Points and I just wanted to see them without the value assigned to them. The Documentation does not say that all `{xi,yi,}` values must be different, so I assumed `ListPlot3D` has the built in intelligence to... |
| Hi, I have a vector field in Cartesian coordinates where all field components depends on all three `(x,y,z)` coordinates. I need t express it in a specific cylindrical coordinate system where the origo of the new system is on the cartesian z-axis,... |
| Thanks Mr. Lichtblau. Next Monday I can upload an OS X panic file I sent to Apple if that helps catching the bug. |
| Hi, Recently I upgraded to OS X 10.13.1 and since I have been having strange freezes of the machine caused by Mathematica. For example, I have a fairly large `List`, about 65000 points, for `ListDensityPlot3D`. The command to show the List is... |
| Hi, I am using this line to plot a magnetic field : ReplaceAll[ crossSectionFieldPlot["\[ScriptCapitalH]", nqvrbmmf[mm0, a, b, c, x, 0, z][[{1, 3}]] ], {mm0 -> 10^6, a -> 0.01, b -> 0.01, c -> 0.01}] ... |
| I query the `PropertyAssociation` of the `rectangular bar magnet` this way: ![See image][1] The `magnetic flux density` already looks bad. I think the `\[RuleDelayed]` for the `M` vector needs a closing curly brace "}". Addition to that, when... |
| Thanks Gianluca Gomi! Your reply helped a lot. |
| Neil, When I want to use the function I get after the partial derivations, I run into a substitution problem wether I use plain or Quantity wrapped constants. Evaluate[Norm[rbmmf[{0, y, z}, {1, 1, 2}]]] or Evaluate[Norm[ ... |
