| precise direction of a radio signal? | 30 May 2007 05:25 GMT | 4 |
Is it possible to determine the direction of a radio signal instantly, i.e. without having to sweep some directional antenna? Perhaps by using several orthogonal antennas, for example? If it helps, here's the particular application I have in mind: I'm

| How to measure a highly intense Alternating Mag Field of 100kHz and 200Gs? | 25 May 2007 11:33 GMT | 3 |
Dears I've got an intense mag-field (f=100kHz, amplitude=200Gs), but no suitable detectors could be applied to it to make an acuurate measurement.

| high school physics problem | 23 May 2007 07:59 GMT | 3 |
Power is generated at 24kV at a generating plant located 118 km from a town that requires 50 MW of power at 12 kV. Two transmission lines from the plant to the town each have a resistance of 0.10 Ohm/km. What should the output voltage of the transformer at the generating plant

| On the interaction between free electrons and EM radiation | 11 May 2007 22:54 GMT | 4 |
Are free electrons invisible? I conducted the thought-experiment wherein an electron orbiting a nucleus is energized by radiated EM such as for example visible light, sending it into a higher orbit around the nucleus. My conclusion was that the energy isn't stored in the electron ...

For simplicity, and as a starting point, let's assume I know how triphase asynchronous motors do work. Well, idealizing like in a gedanken,

| Theories on Electromagnetism | 08 May 2007 01:08 GMT | 16 |
I was pondering to myself why light moves. If a photon has not mass and no known force pushing it then why does it move? The speed of light is known to be 186,282,397 miles per second. But why is it this speed and not, for example 197,527,698 mps?

| HF transformer core losses reduce with reduction in magnetization path | 07 May 2007 11:25 GMT | 1 |
I have two Metglas C cores forming a high frequency transformer O core. I found that wrapping primary and secondary windings on the same bobbin as opposed to wrapping them on separate bobbins on opposite sides of the core has a profound improvement in transformer

| Circularly polarized light produces antisymmetric stress components when absorbing | 01 May 2007 18:08 GMT | 1 |
This is shown in the paper "Spin_produces_stress" (www.sciprint.org). Besides, it is shown that the total torque acting on the absorber equals two powers divided by the frequency. This fact contradicts the standard electrodynamics, which predicts the torque equals power
