Hi, Badly need some help. I am drwaing magnetic field of star (3 wires in angle 120=B0 among them, they stich in point (0,0)). I got equations with Biot-Savart for each wire, but how to make plot in just specific part. So how to write to get just ContourPlot of f=f(x,y) for x>0 ? Because there is no field of it in left part of plane... And then i would sum plots for all wires, once i settle that problem. Any suggestion ? Thanx.
