Determine the length of the wire from which the coil is made…?
A generator uses a coil that has 117 turns and a 0.517 T magnetic field. The frequency of this generator is 45.0 Hz, and its emf has an rms value of 115 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil [...]

I’m trying to find out how many turns of a wire denote the electrical output of a generator. Also, to have 60Hz, I’m assuming that the field needs to be broken 60 times per second? So, a larger number of magnets passing the coil would reduce the speed needed to generate 60 Hz? I’ve looked around [...]

An electric generator consists of a rectangular coil of wire rotating about its longitudinal axis which is perpendicular to a magnetic field of B = 1.60 × 10-2 T. The coil measures 12.00 cm by 21.00 cm and 100.00 turns of wire. The ends of the wire are connected to an external circuit. At what [...]
