A current loop lies in the xy plane of an xyz coordinate system, with the current circulating counterclockwise when viewed looki
ng down the positive z axis toward the origin. The loop experiences a torque about the x axis that is counterclockwise when viewed looking down the positive x axis toward the origin. Part A Describe the direction of the uniform external magnetic field responsible for this torque.

Answer:
The force of the car engine.
Explanation:
The work- energy theorem states that the work done on an object is equal to the change in its kinetic energy. Its expression is given by :
Also, W = F.d
Where
F is the force applied by the engine of car
d is the displacement
m is the mass of an object
u is the initial speed
v is the final speed
So, the force of the car engine increased the car’s kinetic energy. Hence, this is the required solution.
