Task 30505.
The solenoid has a length l = 0,6 m and the cross section S = 10 cm ^ 2. At a certain strength of the current flowing through the coil, the solenoid creates a magnetic flux F = 0,1mVb. What is the energy W of the magnetic field of the solenoid? The core is made of non-magnetic material and the magnetic field is homogeneous throughout the entire volume.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
