Schematic diagram for single phase ac generation

Schematic diagram for single phase ac generation A multi-turn coil is placed inside a magnet with an air gap as shown in above Fig.. The flux lines are from North Pole to South Pole. The coil is rotated at an angular speed, ω = 2π n (rad/s).

N = 60 n = speed of the coil (rev/min, or rpm)

l = length of the coil (m)

 b = width (diameter) of the coil (m)

T = No. of turns in the coil

horizontal position. So, also is the value of induced emf as stated earlier. The maximum value of the induced emf is,
