(a) What is the maximum torque on a 150-turn square loop of wire 18.0 cm on a side that carries a 50.0-A current in a 1.60−T field? (b) What is the torque when θ is 10.9∘ ? Find the current through a loop needed to create a maximum torque of 9.00 N⋅m. The loop has 50 square turns that are 15.0 cm on a side and is in a uniform 0.800− T magnetic field. Calculate the magnetic field strength needed on a 200-turn square loop 20.0 cm on a side to create a maximum torque of 300 N⋅m if the loop is carrying 25.0 A.

a. A conducting bar is bent into a U-shape as shown below, with a sliding conductor placed across it. The sliding conductor moves at a constant velocity v→ = 100 ms in the presence of a time-varying magnetic field, B→ = a^z0.05 sin⁡(1000πt) T. If d = 0.5 m, determine the total emf developed in the loop at t = 3.25 ms. In what direction would current be at this time? Answer: Vemf = +19.8 V, current is CCW b. A square loop of wire is 25 cm on each side and has a resistance of 125 Ω/m. The loop lies in the z = 0 plane with its corners at (0, 0, 0), (0.25, 0, 0), (0.25, 0.25, 0), and (0, 0.25, 0) at t = 0. The loop is moving with velocity vy = 50 m/s in a B-field given by B→ = a^z8 cos⁡(1.5×108t − 0.5x) μT. Determine a function of time which expresses the ohmic power being delivered to the loop and then evaluate the expression at t = 5.00145281 ms. Answer: 20.9 W

A flat, 179-turn, current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 4.53 cm2 and the angle between its magnetic dipole moment and the field is 32.3∘. Find the strength B of the magnetic field that causes a torque of 2.27×10−5 N⋅m to act on the loop when a current of 2.07 mA flows in the loop. B = T
