the speed of rotation      of the shaft is 500 rad/s, then the
voltage induced in the rotating loop will       Since the
external battery voltage is only 48 V, this machine is operating
as a generator, charging the battery.    • Step 2 of 4      (b)
The current flowing out of the machine is approximately
(Note that this value is the current flowing while the loop is
under the pole faces. When the loop goes beyond the pole faces,
eind will momentarily fall to 0 V, and the current flow will
momentarily reverse. Therefore, the average current flow over a
complete cycle will be somewhat less than 5.0 A.)    • Step 3 of
4      (c) If the speed of the rotor were increased to 550
rad/s, the induced voltage of the loop would increase to
and the current flow out of the machine will increase to    •
Step 4 of 4      (d) If the speed of the rotor were decreased to
450 rad/s, the induc
