Solving a problem in physics section 64 point 20 electr

20. The solenoid contains N = 600 turns. Cross-sectional area of the core S = 8 cm2. By winding a current flows, creating a field with induction B = 5 mT. Determine the average value of the emf self-induction, which occurs on the solenoid terminals when the current is reduced to almost zero during Δt = 0,6 ms. The core is made of a nonmagnetic material.
