![]() "Richard Casady" wrote in message ... .. This has **** all to do with the earths magnetic field, which rotates with the earth. Casady The source of the field rotates with the earth. The field itself is decoupled from the source once it leaves the source. An single flux line, as it expands into space, does not rotate with the earth. (How would it know the motion of its source after it left it? This would require some type of messenger wave capable of superluminal velocities). Think of a brief flash of light toward the heavens given off by a flashlight aimed skyward on the surface of the earth. Is the light's path a straight or curved?(To the observer on earth it appears curved opposite to the rotation of the earth). But is it straight or curved in space? Does the light pulse continue to rotate with the earth? Now think of a series of pulses, do any of them rotate with the earth? If the earth were suddenly to reverse rotation would all the pulses emitted before the rotation change suddenly change their curvature? So the earths magnetic field does not rotate with the earth. It expands out into space at the speed of light based upon the location/orientation of its magnetic source at the instant it was created. Once it moves out of the source, the source has no influence upon it. Likewise with charge. A slowly spinning charged sphere does not have curved lines of force. So how are you going to get 200 V/m from a wire? You can't. The wire shorts the field, the voltage at the ends and all over it are equal because it is a conductor. That 200 V/m figure is a high impedance electrostatic field. One way to develop voltage across a conductor is to cut magnetic lines of force, which my method does. Bill |
