Capa 10 1 . [1 point, 10 tries] The flexible loop in the figure below has a radius of 11.1 cm and is in a magnetic field of strength 0.146 T. The loop is grasped at points A and B and stretched until it closes. If it takes 0.215 s to close the loop, find the magnitude of the average induced emf in it during this time. Answer: 2 . [1 point, 10 tries] A square, single-turn wire coil L = 1.26 cm on a side is placed inside a solenoid that has a circular cross section of radius r = 2.88 cm, as shown in the figure below. The solenoid is 18.7 cm long and wound with 144 turns of wire. If the current in the solenoid is 3.47 A, find the flux through the coil. Answer: If the current in the solenoid is reduced to zero in 2.55 s, calculate the magnitude of the average induced emf in the coil. Answer: 4 . [1 point, 10 tries] A single-turn circular loop of radius R = 0.248 m is coaxial with a long 1740 turn solenoid of radius 0.0570 m and length 0.655 m, as seen in the figure below. The variable resistor is changed so that the solenoid current decreases linearly from 6.56 A to 1.50 A in 0.160 s.

Capa 10 Calculate the induced emf in the circular lop. (The field just outside the solenoid is small enough to be negligible.) Answer: 5 . [1 point, 10 tries] The figure below shows a stationary conductor, whose shape is similar to the letter "e" ( a = 57.1 cm), that is placed in a constant magnetic field of magnitude B = 0.505 T directed out of the page. A 57.1 cm long, straight conducting rod pivoted about point O rotates with a constant
