On the non-magnetic cylindrical shell section 20 cm ^ 2 is wound a coil of wire with a diameter of 1 mm and a length of 140 m. The coils of the wire tightly adjacent to each other. At a certain current strength flowing through the coil, it creates a linkage 6 DHS. Find the magnetic field energy of the coil. The magnetic field around the extent considered uniform.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
