current in the solenoid changes as I = 2.00 sin(120t), 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.)
4. The figure below shows an end view of a single-turn square loop of metal wire in the center of and coaxial with a very long solenoid with
a circular cross section. The solenoid is 21.0 cm long, has a radius r = 3.00 cm, and consists of 118 turns of wire. The length of each
side of the square loop is l = 1.50 cm.
(a) The current in the solenoid is 4.00 A. What is the magnetic flux through the square loop (in T • m2)?
6.335*10**/
T. m2
(b) The current decreases from 4.00 A to zero in 4.00 s. What is the magnitude of the average induced emf in the square loop (in V)
over this time?

The current in the solenoid changes as I = 2.00 sin(120t), where I is in amperes and it 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.) 8 = -0.75 cos(1201) * 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? Watch t
