Shap3d32.dat, 32nd 'shape' file for CPO3D

A circular magnetic field inside a torus, to illustrate the option for a 'coiled' magnetic solenoid along an arc of a circle.

Superseded in Oct 2012 by shap3d35, which uses the option for users equations.


A closed magnetic field is created inside a torus, which is taken from shap3d18.


The magnetic field in each quarter is created by using 100 individual thin hoops, placed along an arc of a circle.


To see the magnetic field go to the xy view and click on contour/magnetic/vector. To remove some large fields at points near to the hoops, make the 'maximium magnitude' 0.11. The fields in the vicinity of an individual hoop can be seen by zooming.
