A coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 1.80 cm and 1.00 x 10³ turns/meter (see figure below). The current in the solenoid changes as I = 3.00 sin(120), where I is in amperes and t is in seconds. Find the induced emf (in volts) in the 15-turn coil as a function of time. (Do not include units in your answer.) E- -6.9 cos(120) x How does Faraday's law relate the induced emf to the flux through the coil and the number of turns of wire? What is the magnetic field of a solenoid? Where is it zero and nonzero? How does this affect the calculation of the magnetic flux? Be careful with signs, and with taking the derivative of the function of time. 15-turn coil Need Help? Read it Watch it
