External Fields

The simulation shows a current carrying wire embedded in an external field, B = 0.75*y  i  + 0.75*x  j.   The resultant field is the vector sum of these two fields. Drag the wire and observe the force vector and the force/length on the wire in the yellow message box in the lower left hand corner.  Start

Caution: The script author should insure that external fields have a divergence of zero.
