Task id279
The solenoid is 20 cm long and 4 cm in diameter and has a dense three-layer winding made of wire with a diameter of 0.1 mm. A current of 0.1 A flows through the solenoid winding. The dependence B = f(H) for the core material is shown in Fig. 41. Determine the field strength and induction in the solenoid, the magnetic permeability of the core, the inductance of the solenoid, the energy and volumetric energy density of the solenoid field.
