Model

Coil (Cur) is wound on the ferrite core (Ferrite).

 

The coil’s form is given by the following equations.

 

x = ( A*sin(t*N) + B ) * cos(t)
y = ( A*sin(t*N) + B ) * sin(t)
z = A*cos(t*N)
A: The radius of the coil.
B: The distance from the center of the toroid to the center of the coil
N: The number of turns of the coil
t: Angle
