Bruce Harvey 's Alternative Physics site New:- A Classical Quantum Theory New:- The classical Atom Summary I believe that subtle errors in 19th Century Physics have caused a build up of cumulative errors until physics now out-weirds science fiction. This is my attempt to find the Unified Laws of Physics I have a consistent theory which explains the phenomena of Electromagnetism, Newtonian Mechanics and Gravity. (In paper 5 , I use Classical physics to account for the so called relativistic effects of the increase in mass, the Lorentz contraction and the slowing of clocks which SR accounts for. I also account for the effects of the slowing of clocks and gravitational red-shift by gravitational potential and the bending of light by gravity.) We start with the Pure Charge Model of Matter . This theory looks at a universe constructed of nothing but space and sees how electrons and quarks could be formed and used as basic building blocks for matter. Such a model exhibits inertial and gravitational properties identical to the real universe. Newtons Laws of Motion can be derived from the basic properties of space and the nature of pure charges.

A stationary charge has an electric field. A moving charge can produce a magnetic field. Just as gravity accelerates masses, electric and magnetic fields can accelerate charges. When accelerated, charges give off ( emit electromagnetic radiation

Building an electric motor in 10 minutes. The single brush motor. A bigger motor. The double brush improvement. ... A railgun in 10 minutes A motor with two coils In this section we will construct a motor without any permanent magnets. In place of the magnet, we will use another coil of wire. This coil is called the field coil, and the coil that moves is called the armature coil. The simplest way to do this would be to replace the permanent magnet with a coil of wire connected to a second battery. But we can save the second battery, and waste less electricity, by arranging the coils as shown in the diagram below: The diagram shows how the electrons flow in the coil. They start where the negative terminal of the battery is connected (marked here with a minus sign). They then flow around and around inside the field coil until they come to the first support loop on the right. From there they flow into the armature coil, going round and round until they come out the other end, and flow into the second support loop on the left. From there they travel back to the positive terminal of the battery. You can see that when the electricity flows in one coil, it also flows in the other. When the armature turns over, and the insulation cuts off the flow of electricity to the armature, it also cuts off the flow of electricity to the field coil at the same time.

Electromagnetism What is Electromagnetism? Electromagnetism describes the relationship between electricity and magnetism. Nearly everyone, at some time or another, has had the opportunity to play with magnets. Most of us are acquainted with bar magnets or those thin magnets that usually end up on refrigerators. These magnets are known as permanent magnets. Although permanent magnets receive a lot of exposure, we use and depend on electromagnets much more in our everyday lives. Electromagnetism is essentially the foundation for all of electrical engineering. We use electromagnets to generate electricity, store memory on our computers, generate pictures on a television screen, diagnose illnesses, and in just about every other aspect of our lives that depends on electricity. Electromagnetism works on the principle that an electric current through a wire generates a magnetic field. This magnetic field is the same force that makes metal objects stick to permanent magnets. In a bar magnet, the magnetic field runs from the north to the south pole. In a wire, the magnetic field forms around the wire. If we wrap that wire around a metal object, we can often magnetize that object. In this way, we can create an electromagnet.

Essay On The Unified Theory Of The Classical Fields Of Gravitation And Electroma A new attempt to establish a unified theory of the classical fields of gravitation and electromagnetism which complies with the geometric paradigm of the theory of relativity of Albert Einstein. http://www.e-kr.org

Essay on the Unified Theory of the Classical Fields of Gravitation and Electromagnetism After the publication of the general theory of relativity in 1916, Albert Einstein tried to establish a unified theory of the classical fields of gravitation and electromagnetism. Although he published many attempts on the subject until 1955, it is sadly wise to say that he did not succeed. We would like to introduce a new attempt to establish a unified theory of the classical fields of gravitation and electromagnetism which complies with the geometric paradigm of the theory of relativity of Albert Einstein. The theory we shall describe is geometrically unified in the sense that the fields equations, and the Hamiltonian function from which they derive, are formally unified entities (i.e. they are not the sum of several independent parts) which depend only on the metric of the particular spacetime being considered.
