Solution to task 475 from Chertov´s for extramural stud

475. The solenoid contains N = 800 turns. The cross-section of the core (made of non-magnetic material) S = 10 cm2. A current flows through the winding, creating a field with induction B = 8 mT. Determine the average value of e. etc. with. self-induction, which occurs at the terminals of the solenoid, if the current decreases almost to zero during the time Δt = 0.8 ms
