Решение задачи по физике раздел 33 пункт 60 электро

60. In the iron core in the form of a torus having an average diameter d = 70 mm is wound with the winding total number of turns N = 600. The core is made narrow transverse slit width b = 1,5 mm. When a current through the winding I = 4 A magnetic induction into the slots B0 = 1.5T. Neglecting scattering field at the edges of the slots determine the permeability of iron for the given conditions.
