Task 30302.
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, 1 DHS. 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.
