Physics: Solenoid/ Generator question?
Suppose that you wish to construct a simple ac generator with an output of 12 V maximum when rotated at 60 Hz. A magnetic field of .050 T is available. If the area of the rotating coil is 100 cm^2, how many turns are needed?

What is the orientation of the armature loop in a simple ac generator when the following is true. Explain your reasoning for each situation, and discuss why they do not occur at the same orientation. (a) the value of the emf is a minimum (b) the value of the magnetic flux is a minimum Hi! this is [...]

I am researching AC electric generators, and have seen three different descriptions for the simple design. So I written these three choices up myself, and want to know which is most common: A. Wire windings as stator, more coils of wires as rotor. Current fed to rotor, become electromagnet and produces magnetic field, rotates (through heat, [...]

I have made these two choices up myself, as I know it should be either one of these but I don’t know which one… A. Stator windings, coils of wires as rotor. Current fed to rotor, become electromagnet and produces magnetic field, rotates (through heat, wind etc) and induces current in stator windings which AC. B. Permanent [...]

Is it in the number of coils? For an AC generator, how does the coil continually rotate up and back down again? Does it have to do with force from a magnetic field? Any diagrams helpful. Thanks.

I’m building a special AC generator that will have induced current running at 60 Hz. I was wondering, I’m trying desperately to reduce eddy currents (another member on here suggested Ferrite material). Another thing is hysteresis loss… Any material out there that has high magnetic permeability, as well as low hysteresis and [...]

Thursday, April 8, 2010
Imagine a piece of metal wound in a solenoid connected to an AC generator, when the generator is turned on, edd currents are produced, and the metal is heated, why is it heated? And what energy is wasted? Also, magnetic damping? If I drop a single loop into a magnetic field a force opposes the motion [...]

Saturday, April 3, 2010
( Just the basics? ) Why does the armature spin continuously in both? I really do not understand , why does the current alternate in an AC generator anyways? how do the slip rings work ?
