Question

A simple DC electric motor is shown below. The motor is carrying a DC current I= 5 A. The stator, or stationary magnetic, produces a uniform k field loop of

the rotor has an area A=1cm². The can be assumed to be in the z = 0 plane,as such that the normal to the loop is â̟. The currents through the rotor are "commutated", such that it is always flowing in a clock-wise direction, as show m. a) Determine the torque on the wire loop (rotor) in its current position. b) If the rotor rotates 90 degrees, such that the normal is â.,determine the torque on the loop.
