Here ,
direction of magnetic field is to the right
for the loop ,
direction of the area vector of the loop vector is perpendicular to the area
the direction of area vector is OUT of the page.
as the torque is given as
Torque = u0 * N * I * area X magnetic field
as magnetic field and area vector are perpendicular to each other
there will be a magnetic Torque acting on the loop
hence , the engineer should not be fired

The L-shaped object(Figure 1) can be rotated in one of the
following three ways: case A, about the x axis; case B,
about the y axis; and case C, about the z axis
(which passes through the origin perpendicular to the plane of the
figure).
If the same torque ? is applied in each of these cases,
rank them in decreasing order of the resulting angular
acceleration.

(c20p24) A single loop of area 0.193 m2 is placed perpendicular to a magnetic field of 0.334 T. The loop is rotated about an axis lying in the plane of the loop and passing through its center. An instantaneous emf of 8.21 Volts is generated when the plane of the loop makes an angle of 45 o with the field direction. What is the angular speed of the loop (rad/s)?

An AC generator with armature loop area of 0.1 m2 and 20 turns, rotates the armature at 60 Hz within a static magnetic field with magnetic flux density of 0.2 T. A) Using V_emf^m=NAωB_0 sinωt, include below the appropriate numeric expression for V_emf^m as a function of time including units. (Hint: The peak emf voltage should be between 140 and 160 V.) B) Using MATLAB, plot the V_emf^m expression derived for part (a.) for time t ranging from 0 to...

The L-shaped object in the figure can be rotated in one of the following three ways: case 1, rotation about the x axis; case 2, rotation about the y axis; and case 3, rotation about the z axis (which passes through the origin perpendicular to the plane of the figure.) Rank these three cases in order of decreasing moment of inertia. Rank from largest to smallest. To rank items as equivalent, overlap them.
