A 8-turn generator coil with area 0.155 m^2 rotates in a 1.20 T magnetic field. At what frequency should the coil rotate to produce a peak emf of 150, expressed four sig figs with approp units.
Attached are self notes. If you help me with the symbology... I know that f = frequency. I am not at clear the other symbols.
J: Refer to figure la 2.0m conductor is shown, that rotates at 1200 rev/min in the radial field
B = 0.10 sinpa, T. Solve the current in the closed loop with a resistance 100 N.
Discuss the polarity and current direction.

the induced voltage is the rate of change in the magnetic
field with respect to time. A rapid change in the flux induces a high voltage. Similarly, a slow
change in the flux produces a low induced voltage.
What HaveI Learned So Far?
1. What is the effect of increasing the number of loops to the magnitude of the induced
EMF?
2. What will happen to the magnitude of the induced EMF if the number of loops will be
decreased?
3. How does making the magnetic flux faster affect the magnitude of the induced EMF?
How about when make the magnetic flux slower?
