Profiles the magnetic field along a selectable curve for a helical (solenoidal or toroidal) current loop using the Biot-Savart law. The Biot-Savart line integral is represented first symbolically in terms of a parametric path in three dimensions, then converted to a function of the parameter and integrated numerically. The results are compared to analytic results for an ideal solenoid or toroid.
