The coil in an electric generator has 150 loops and each loop has an area of 2.5 x10^-3 m2. It is desired that the maximum emf of the coil be 240 V when it rotates with an angular frequency of 60 Hz (60.0 cycles per second).Find the strength of the magnetic field, B, required for this generator to operate at the desired voltage.
