The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); " an electric field can also be created by a changing magnetic field... and a magnetic field by a changing electric field... no charges needed. In Maxwell's displacement current were charges (electricity). In the space no charged bodies. But what produce very slow charge? a charge is a charge, it can neither be created nor destroyed.... well except maybe by matter-anti-matter annihilation. charged particles can move at any speed from 0 to c, nothing special about speeds. Charged particles can move at any speed from 0 to c and always produce the electric field. Why not? Next Wiki weote: "From a classical perspective, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner ;" It is important to know that Maxwell's waves are rotational (oscillating magnetic whirl). no they aren't... at least not all of them. maxwells equations are just as well satisfied by linearly polarized (magnetic AND electric field) waves. Maxwell's waves are transversal. It means that something oscillate around the axis of rotation. Linear polarization means thet the rotating oscillations are in the one plane. Alternate electric field also propagate in a wavelike manner. But here to and fro (no rotations). if the magnetic field is rotating then the electric field also rotates. they always go together. In Maxwell's Hypothesis. The fundamental question: Are radio waves a simple electric waves or the very sophisticated Maxwell's waves? ALL radio waves can be described by maxwell's equations, both simple linear polarized ones and circularly polarized ones. Wiki wrote: " FM radio The term "circular polarization" is often used erroneously to describe mixed polarity signals used mostly in FM radio (87.5 to 108.0 MHz), where a vertical and a horizontal component are propagated simultaneously by a single or a combined array." It seems that radio waves are the electric waves. If yes, the light is also longitudinal. S* |

ALL radio waves can be described by maxwell's equations, both simple linear polarized ones and circularly polarized ones. The fundamental question is really how can we describe this "wave".? A wave of what "water", A wave of "water" traveling towards a beach. Is it water we are really trying to describe or what? Water has a "skin" on its surface , a skin that encasulates it like a bag , container or a boundary! Water waves are described by Stokes: http://en.wikipedia.org/wiki/Stokes_drift Nothing is clear when describing a "wave" with respect to physics, as it is just a "F" word to substitute an unexplainable in a psuedo description There is no agreement what so ever as to what a "wave" is so there cannot exist a description of what radio "IS", "IS"!. Physicists acknowledge that radio is some thing that is unexplanable leaving just hams to fill in the unexplainable about radio and to deny the explanations made by others. What we do have is a string of mathematical equations all of which interlock which are a result of observation and seamingly reasonable deductions. Maxwell deduced b y examination of units used that a portion of his formula was also a mathematical explanation of elevation and acceleration but no description of what! Maxwell did it. Maxwell described it in English. The equations wrote Heaviside. A physicists named Gauss who provided a lot of Maxwells tools used Newtons laws to establish boundary laws where it can be seen that mathematically a clump of static particles in equilibrium could be made dynamic by adding a time varying field while retaining equilibrium meshes with Maxwells equations on radiation. So who on earth descided to interject "waves" into the discussion and why? The dynamic particles are waves. The Gauss time varying field is the longitudinal wave. And what experiment was performed that dictated its inclusion in the subject of radio or radiation that has put a screaming halt to a sustainable explanation of same for more than a hundred years where other dreams have come to fruition by utelizing the human brain. Is it the ham population that is responsible for the lack of advances in the advancement of science by denying the inclusion of particles as the basic matter involved in elevation and acceleration (displacement) as implied by Maxwell's equations, preferring instead to use 'water' and 'waves' to describe the science to the non initiated. The water and waves are usefull in schools. Everybody can see. Light, radio waves and sound waves are analogous in the all details. Sound waves and radio waves are not visible but many experiment was done. S* |

you mangled the replies so badly that i couldn't even follow what you were saying. light and radio waves are the same thing, as are gamma, infra red, x-ray, etc... all the exact same phenomena explained very well by maxwell's equations. scientists for 100 years have been unable to come up with anything better, you aren't going to by your misguided assertions that have no mathematics or experimental evidence behind them. sound waves and water waves are VERY different things. while some of the equations take the same form because they share sinusoidal repetition properties, the underlying physics is VERY different. you have to abandon the analogies you learned in elementary school and learn the proper physics to understand why electromagnetic waves are not like sound or water... start with this, why can you polarize light or radio waves but not sound waves? |

A whip antennas on a car is not such? no, the other half of the dipole is the body of the car itself. Why the dipoles exhibit the directional pattern? because they do, its well measured and accurately described in the equations. Are the measured and the calculated from the equations in agreement? yes, to within many, many decimal places... if they did not agree to within the limits of measurement then someone would have had to make a new theory to explain the difference. |

I am happy about that but it doesn't help me to understand em waves or where they are involved with Maxwell. It is inbuilt in physics that we are accelerating a charge where acceleration demands mass. But there is no continuation of explanation beyond that point. Every theory since classical has broken down and we are now in the superstring theory while at the same time trying to collide the smallest particle on earth which determines the speed of light. You definitely can not involve acceleration without mass, and gravity can only be canceled by a reactionary vecto r being involved and you cannot have a straight line trajectory without two vectors representing gravity and its associated spin. Frankly, we should start again using the basics of Newton as used by Maxwell and then backtracking to the time of Einstein by supplying the relationship of static and dynamic fields so that frausteration did not drive us away from former progress in physics over the centuries to invent particles without mass, anti particles and acceleration of string which can take on the shape of a wave. What startles me is the acceptance of computer programs based on Maxwell which clearly show that the radiating member must have zero resistance for maximum radiation. That radiation resistance implies that of an encapsulating substance which is elevated and accelerated by the action of displacement current in a similar manner to scrap metal sorting yards. Now I read that present particle science is retracting to the idea of a single particle being the source of the standard model and where the existing environment is creating the observences at any point in time based on the existance of matter in all cases. It is time we reverted back to the demands of equilibrium where an "equal" sign addition to any equation demands that the addition of all used in that equation must equal zero. Which is a staple of all that is used by the human race over the centuries. Not one of many theorems on radio have come to fruition with the use of integra ated solutions to satisfy the whole. All we have are totally disconnected imaginations spawned by using mathematical tricks of doubtful merit with imaginary inventions to fill in the inevitable gaps. We only have one tool that is solidly connected to equations of maxwell and that is the computer programs with optimizer that adheres solely to the stated equation together with adherence to equilibrium. What better place exists to delve further into the Masters thoughts rather than the manufacture of another theorem? |
