An electric motor has 72 turns of wire wrapped on a rectangular coil, of dimensions 3cm by 4cm. Assume that the motor uses 14A of current and that a uniform 0.5T magnetic field exists within the motor.

1)What is the maximum torque delivered by the motor? Answer in units of Nm.

2)If the motor rotates at 3000 rev/min, what is the peak power produced by the motor? Answer in units of W.

any help is appreciated! thanks

Max torque will be at 90 degrees to the plane of B.

Torque= current*turns*area*B

area is in square meters.
