A square current loop 5.20 cm on each side carries a 450 mA current. The loop is in a 0.800 T uniform magnetic field. The axis of the loop, perpendicular to the plane of the loop, is 30° away from the field direction. Part A What is the magnitude of the torque on the current loop?

There are three long, straight, parallel wires depicted, all lying in one plane and carrying current in an upward direction. Find the force exerted on a 30-cm segment of wire B if I = 10 A, r₁ = 2.0 cm, and r2 = 2.0 cm. F = μA Value A B Three parallel wires Submit Request Answer I 13 A Express your answer with the appropriate units. Enter a positive value if the force is rightward and a negative value if the force is leftward. 1₂ Units C ? 22 A
