Solving a problem in physics section 63 point 37 electr

37. The cross-section with an iron core solenoid S = 10 cm2; coil length l = 1 m. Find the magnetic permeability μ of the core material, if the magnetic flux penetrating the cross section of the solenoid, F = 1.4 DHS. Which current I, the current through the solenoid corresponds to the magnetic flux, it is known that the inductance of the solenoid under these conditions, L = 0,44 TR?
