Solving a problem in physics section 63 point 40 electr

40. The coil length l = 50 cm is inserted into the core of such an iron grades for which the dependence of B = f (H) is unknown. The number of turns of the solenoid per unit of length n = 1 400 mm-sectional area of the solenoid S = 10 cm2. Find the magnetic permeability μ of the core material at a current through the solenoid coil I = 5 A, if it is known that the magnetic flux penetrating the cross section of the solenoid core, F = 1.6 DHS. What is the inductance L of the solenoid under these conditions?
