4. The rectangular loop in the drawing consists of 52 turns and carries a current of I = 2.6 A. A 1.6-T magnetic field is directed along the +y axis. The loop is free to rotate about the z axis. (8 = 23°) N tums 0.70 m 5. 6. (a) Determine the magnitude of the net torque exerted on the loop. (No Response) N.m (b) State whether the 23° angle will increase or decrease. C the angle increases the angle decreases 6. The coil in the figure below contains 409 turns and has an area per turn of 3.00 x 10³ m². The magnetic field is 0.25 T, and the current in the coil is 0.27 A. A brake shoe is pressed perpendicularly against the shaft to keep the coil from turning. The coefficient of static friction between the shaft and the brake shoe is 0.84. The radius of the shaft is 0.013 m. What is the magnitude of the minimum normal force that the brake shoe exerts on the shaft? (No Response) N 7. A long solenoid has a length of 0.66 m and contains 1395 turns of wire. There is a current of 5.9 A in the wire. What is the magnitude of the magnetic field within the solenoid? (No Response) T -0.50
