Задача 30732.

A solenoid with a cross section of 20 cm^2 and a length of 40 cm with a core of non-magnetic material contains 800 turns. Find the inductance of the solenoid, the total magnetic flux coupled to the solenoid, and the energy of the magnetic field if a current of 2 A flows through the turns.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
