A 60.0-Hz generator delivers an average power of 75 W to a single light bulb. When an induced current exists in the rotating coil of a generator, a torque—called a countertorque—is exerted on the coil. Determine the maximum countertorque in the generator coil. (Hint: The peak current, peak emf, and maximum countertorque all occur at the same instant.) Answer: 0.4 Nm

A 10.0-cm side square loop is fashioned from a single 4.00-m long, 100-g wire. One side of the loop is attached to a horizontal, frictionless axle. The loop is suspended in a region with a uniform 10.0-mT magnetic field oriented vertically. (a) What angle does the loop make with the vertical when it carries a current of 3.40 A? (b) What magnetic torque acts on the loop? Please don't just copy the other tutors, majority of their answers are wrong.

A simple generator has a square armature 5.0 cm on a side. The armature has 70 turns of 0.59-mm-diameter copper wire and rotates in a 0.700-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. Part A: At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature. Express your answer to two significant figures and include the appropriate units.
