Question

A rectangular loop with a length of 0.600 m, width of 0.400 m, and consisting of 180 tightly-wrapped turns is hinged along the y-axis and placed in a uniform magnetic field such that the plane of the loop makes an angle of 35.0

A rectangular loop with a length of 0.600 m, width of 0.400 m, and consisting of 180 tightly-wrapped turns is hinged along the y-axis and placed in a uniform magnetic field such that the plane of the loop makes an angle of 35.0 A degree with the x-axis (see figure below). The magnetic field has a magnitude of 0.872 T and points in the positive x direction, and the current in the coil is 1.25 A. Correct: Your answer is correct. There are two diagrams, the second diagram is a top view of the first diagram. The first diagram shows the x y z coordinate space, with a rectangular loop with its bottom left corner at the origin. The loop then runs up the positive y axis for a distance of 0.6 m, and then runs out a distance of 0.4 m at an angle of 35 degrees away from the positive x axis towards the positive z axis. The loop then completes the rectangle. Along the top of the rectangle an arrow points away from the y axis and is labeled I = 1.25 A. The second diagram shows the x and z planes, and that the rectangle extends 35 degrees below the x axis. The arrow labeled I points away from the origin in the top view. (a) Determine the magnitude of the torque exerted on the loop. N A? m (b) Determine the expected direction of rotation of the loop. The loop rotates clockwise as viewed from above. The loop rotates counterclockwise as viewed from above. The loop does not rotate.

Explanation / Answer

A = 0.6*0.4 = 0.24 m^2

torque = N*B*A*I*sin55 = 180*.872*.24*1.25*55s
=38.57 Nm

b) The loop rotates clockwise as viewed from above
