DESCRIPTION
Problem 30301.
The solenoid contains N=800 turns. Core cross-section (made of non-magnetic material) S=10 cm^2. A current flows through the winding, creating a field with induction B = 8 mT. Determine the average value of the EMF that occurs at the solenoid terminals if the current strength decreases to almost zero in time t = 0.8 ms.
