AI Thread Summary
A stationary alternator cannot generate current like a transformer without relative motion between the field and armature windings. While alternating current can create a changing magnetic field, voltage generation in an alternator requires movement. The coupling coefficient between the rotor and stator affects output, with maximum coupling occurring when they are aligned and minimal coupling at 90 degrees apart. Therefore, rotation is essential for effective voltage generation in an alternator. Understanding these principles clarifies the differences between alternators and transformers in generating electricity.

will an alternator produce current when both its field and armature windings are stationary(like transformer action),
as ac current produces a changing magnetic field.is the field rotated for making more output?

Relative motion is needed for an alternator to generate a voltage. http://thumbnails112.imagebam.com/37333/0363e9373324851.jpg

If the field is alternating current, then the stator will incur induction like a transformer. But the coupling coefficient between primary and secondary changes with rotor angle. When the stator and rotor poles are directly aligned, coupling is maximized. If the rotor and stator are 90 electrical degrees apart, coupling is minimized. Did I help?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
