## rel·uc·tiv·i·ty

(rĕl′ək-tĭv′ĭ-tē)
n.
A measure of the resistance of a material to the establishment of a magnetic field within it, equal to the ratio of the intensity of the magnetic field to the magnetic induction of the material.

[Blend of reluctance and conductivity.]

Indeed, in [31] a MinRes solver for the solution of multiharmonic eddy current optimal control problems is constructed that is robust with respect to the discretization parameter h and all involved parameters like frequency, conductivity, reluctivity, and the regularization parameter.
In order to solve the nonlinear PDE using the Newton-Raphson method, an estimated solution of the magnetic flux is provided and fed into the ODE, from which the differential reluctivity and the magnetic field are calculated and returned back to the PDE to generate the next estimated solution.
