# Coil Encircling Solenoid#

## Question Text#

A long solenoid with $$n$$ = 13 turns per centimeter has a cross-sectional area of 7 $$\rm\ cm^2$$ and carries a current of 1.00 $$\textrm{A}$$. A coil with 6 turns encircles the solenoid. When the current through the solenoid is turned off, it decreases to zero in 0.04 $$\textrm{ s}$$. What is the average emf induced in the coil?

$$\varepsilon=$$ $$\rm\ V$$
