A magnetic field gradient imposed on the solidifying melt can cause a magnetic force as a result of flux density (B) and Lorentz forces (J × B), where J is the induced current [73, 74]. Fig. 5(a) shows the arrangement of field coils in a DC casting process and the directions of the magnetic field and forces responsible for the stirring effect ...
2 1671: Isaac Newton destroys Hooke's theory of color by experimenting with prisms to show that white light is a mixture of all the colors and that once a pure color is obtained it can never be changed into another color. Newton argues against light being a vibration of the ether, preferring that it be something else that is capable of traveling through the aether.
Properties of Electromagnetic Radiation. Photons: Electromagnetic radiation is emitted as discrete packets of energy called photons. These photons carry light energy and travel at the constant speed of light. Quantized Harmonic Waves: Electromagnetic radiation can be described as quantized harmonic waves.These waves exhibit specific frequencies and energy levels.
Electromagnetism - Discovery, Uses, Physics: Electric and magnetic forces have been known since antiquity, but they were regarded as separate phenomena for centuries. Magnetism was studied experimentally at …
Physical Origin. Earth's magnetic field is mostly caused by electric currents in the liquid outer core, which is composed of highly conductive molten iron. A magnetic field is generated by a feedback loop: Current loops generate magnetic fields (Ampère's law); a changing magnetic field generates an electric field (Faraday's law); and the ...
ELECTROMAGNETIC ORIGIN OF PARTICLE MASSES 121 Equation (9) is valid everywhere outside the region under consideration (outside the absorber). Then at asufficiently large distance from the absorber, the first part in the sum (9) describes electromagnetic "waves" propagating from the absorber, while the
The earliest writings about electromagnetism were in 600 BCE, when the ancient Greek philosopher, mathematician and scientist Thales of Miletus described his experiments …
Electromagnetic radiation released is related to the temperature of the body. Stephan-Boltzmann Law says that if this body is a black body, one which perfectly absorbs and emits radiation, the radiation released is equal to …
Most obvious are the two from which the force derives its name: electricity and magnetism. These were the subject of much investigation and experimentation by 19th century physicists such as...
David Ball discusses how the electromagnetic spectrum was originally mapped out and what this means for spectroscopy. When a person says the word "light," a listener — even …
We propose an approximate theory describing electromagnetism and gravity as a single direct particle interaction. A new element in this theory is the assumption on real simultaneous (combined) existence of retarded and advanced interactions. Another essential principle of this theory is Mach's principle, according to which the interaction of particles in a …
electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies. The electromagnetic spectrum comprises the span of all electromagnetic radiation and …

Electromagnetic radiation - Spectrum, Wavelengths, Properties: The brief account of familiar phenomena given above surveyed electromagnetic radiation from low frequencies of ν (radio waves) to exceedingly high values of ν (gamma rays). Going from the ν values of radio waves to those of visible light is like comparing the thickness of this page with the distance of …
Electromagnetism is an area of physics which involves the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged …
Eager to demonstrate electromagnetic phenomena to his students, Henry built upon the work of English scientist William Sturgeon, who in 1825 discovered that wrapping a wire around an …
Electromagnetic theory is a physics field focusing on electric and magnetic fields' interactions. It shows how charges and currents create forces and electromagnetic waves like light and X-rays, detailing their propagation through space. Electromagnetic theory is based on four fundamental equations, known as Maxwell's equations, that relate the electric and…
Light - Electromagnetic, Wavelength, Spectrum: In spite of theoretical and experimental advances in the first half of the 19th century that established the wave properties of light, the nature of light was not yet revealed—the identity of the wave oscillations remained a mystery. This situation dramatically changed in the 1860s when the Scottish physicist James …
In our papers [1, 2], a theory was proposed in which the origin of mass and gravity are consequences of the electromagnetism.We took as a basis the theory of direct electromagnetic interaction between particles, constructed by Tetrode [] and further developed by Wheeler and Feynman [4, 5].In [], both retarded and advanced electromagnetic interactions …
Consequently the answer to question in TR is that electron mass doesn't have electromagnetic origin but it has electrodynamic nature. Consequently the dualism wave-corpuscle, in the shape of ...
Since organisms have very peculiar electromagnetic properties, it is possible and also probable that the origin of life was based on cooperation between dipolar organic molecules and special ...
The coulombian picture of the origin of magnetic fields was dominant in textbooks until about 1960, and it persists in popular imagery. A revolutionary breakthrough in the history of magnetism came on 21st April 1820, with the discovery of the long-sought link between electricity and magnetism. During a public lecture, the Danish scientist Hans ...

Under the condition of the expansion of the universe and all masses with their charges in it, the electromagnetic origin of the gravitational force is determined with the help of the Lorentz force. Basic physical relations to the interactions of the basic forces of nature are established. This includes calculation formulas for the gravitational constant, the proton radius …

Energy, a measure of the ability to do work, comes in many forms and can transform from one type to another. Examples of stored or potential energy include batteries and water behind a dam. Objects in motion are …
Electromagnetic waves bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. ... traveling in the direction of the positive x-axis with the phase of the wave chosen so that the wave maximum is at the origin at (t = 0), the electric ...
