Well, I know H must be variable because \mu is variable. H=B/\mu So B is variable but B also depends of \mu and r For me B is: B=(\mu*I*N)/(2\pir) so H= (I*N)/(2\pir) This mean that H don't depend of the center material of toroid

Consider a toroidal coil of rectangular section of N turns, for every one of which circulates a stream I. The inner radius of the coil is a and b is the exterior and the height is h. The core of this coil is a material inhomogeneous in such a way that their magnetic permeability just depends on...
