The figure 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 15.0 cm long, has a radius r= 3.00 cm, and consists of 120 turns of wire. The length of each side of the square loop is /= 1.50 cm. The current in the solenoid decreases from 4.00 A to zero in 0.40 s. What is the magnitude of the average induced emf (in pv) in the square loop over this time? 10001010 2020 O a. 2.3 O b. 4.5 O c. 6.3 O d. 1.5 O e. 3.0

5. A 25.0 cm long solenoid has a radius of 3.00 cm and has 2000 turns of wire. The current in the solenoid varies according to the function I (t) = 6t - 8t2, where I is in amperes and t is in seconds; the direction of the current in the solenoid is shown below (clockwise as seen from the left). A copper ring of radius 5.00 cm and resistance 0.200 is placed around the solenoid. What is the magnitude and direction (specify clockwise or counterclockwise) of the current in the copper ring at t = 0.500 s? Isol

A wire with current i = 2.47 A is shown in the figure. Two semi-infinite straight sections, both tangent to the same circle with radius 4.51 cm, are connected by a circular arc that has a central angle 0 and runs along the circumference of the circle. The connecting arc and the two straight sections all lie in the same plane. If B = 0 at the center of the circle, what is 0? 2Connecting arc Number i Units
