The Magnetic Vector Field Made by a Ring of Current
This code finds the vector field, generated by a single ring of current. This is displayed in the XY plane, which works since the field is radially symmetric. It sets up a matrix of points with a height and width centered on the (0,0) point. The ring sits along the Y axis. The ring has a radius of :0.127 M and 800000 AmpTurns inside the coil. Some input is needed:
Plane Height? (suggest: 0.35):0.35
Plane Width? (suggest: 0.65):0.65
Number of cells? :40
The output is the vector field plot. The user can also access the direction vectors and the magnetic field strength (in Gauss). This is saved within the data structure: VectorField.
