Question Text#

A long solenoid with \(n\) = turns per centimeter has a cross-sectional area of \(\rm\ cm^2\) and carries a current of \(\textrm{A}\). A coil with turns encircles the solenoid. When the current through the solenoid is turned off, it decreases to zero in \(\textrm{ s}\). What is the average emf induced in the coil?
