A generator uses 400 loops of area 0.0550 m^2, rotating in a 0.0639 T magnetic field. What angular velocity does the coil need to generate a maximum EMF of 500 V? (Unit = rad/s)

A bicycle generator rotates at 1,975 rad/s, producing a 17.5 V peak emf. It has a 46-turn, 1.00 by 3.00 cm rectangular coil in a 0.640 T field. It is driven by a 1.76 cm diameter wheel that rolls on the outside rim of the bicycle tire. (a) What is the velocity of the bicycle? (Enter the magnitude in m/s.) m/s (b) What is the maximum emf (in V) of the generator when the bicycle moves at 10.0 m/s, noting that it was 17.5 V under the original conditions? V (c) If the sophisticated geherator can vary its own magnetic field, what field strength (in T) will it need at 5.00 m/s to produce a 9.00 V maximum emf?

A generator has a peak voltage of 257 V and its coil with 500 turns and a diameter of 5.18 cm rotates in a 0.226 T field. At what frequency, in rpm, is the generator operating?

Suppose a generator has a peak voltage of 205 V and its 500 turn, 5.5 cm diameter coil rotates in a 0.15 T field.   What frequency in rpm must the generator be operating at?
