At the edges of these large accumulations of dark matter, stellar systems galaxieshot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far. Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.

Collision of galaxy clusters leads to a shock compression of the hot cluster gas and of the magnetic fields. The variant "One day sir, you may tax it. A Selection of Scientific Quotationsp.

According to Snopes in "Long Ago and Faraday"it is most likely an invented quotation, as there are no contemporaneous records, though Lecky did live through the same time as Faraday and Gladstone. Quotes about Faraday[ edit ] Whatever our opinionsthey do not alter nor derange the laws of nature.

Magnetism Quotes (28 quotes)

If the idea of physical reality had ceased to be purely atomic, it still remained for the time being purely mechanistic; people still tried to explain all events as the motion of inert masses; indeed no other way of looking at things seemed conceivable.

Then came the great changewhich will be associated for all time with the names of Faraday, Clerk Maxwelland Hertz. Silver Underneath his sweetness and gentleness was the heat of a volcano. He viewed his discoveries of nature 's laws as part of the continual process of "reading the book of nature", no different in principle from the process of reading the Bible to discover God 's laws.

A strong sense of the unity of God and nature pervaded Faraday's life and work. Jim Baggot, in "The myth of Michael Faraday: Michael Faraday was not just one of Britain's greatest experimenters. A closer look at the man and his work reveals that he was also a clever theoretician" in New Scientist No.

He saw in it a reality of a new category differing from matter. It was capable of transmitting effects from place to place, and was not to be likened to a mere mathematical fiction such as the gravitational field was then assumed to be.

In his opinion, the phenomena of electricity and magnetism should be approached via the field rather than via the charged bodies and currents. In other words, according to Faraday, when a current was flowing along a wire, the most important aspect of the phenomenon lay not in the current itself but in the fields of electric and magnetic force distributed throughout space in the current's vicinity.

It is this elevation of the field to a position of preeminence that is often called the pure physics of the field. Faraday was not a mathematician and was unable to co-ordinate the phenomena he foresaw in a mathematical way, and derive the full benefit from his ideas. Before dying, however, he entrusted this task to his colleague Maxwell ; and one of the most astonishing theories of science, eclipsed only in recent years by Einstein 's theory of relativity, was the outcome. Albert Einstein"Clerk Maxwell's Influence on the Evolution of the Idea of Physical Reality" in Essays in Science Would Faraday have discovered the law of electromagnetic induction if he had received a regular college education?

When his faculties were fading fast, he would sit long at the western window, watching the glories of the sunset; and one day, when his wife drew his attention to a beautiful rainbow that spanned the sky, he looked beyond the falling shower and the many-colored arch, and observed, "He hath set his testimony in the heavens.

There was a philosopher less on earth, and a saint more in heaven. John Hall Gladstonein Michael Faradayp.

Michael Faraday - Wikiquote

It was soon discovered that the conduction of electricity by solutions is accompanied by chemical reactions at the electrodes which serve to conduct the current into and out of the solution. Nicholson and Carlisle demonstrated the decomposition of water into hydrogen and oxygen by a current in Davy's discovery of sodium and potassium metals by electrolysis of moist soda and [caustic] potash was a striking example of the novelty of electrochemical decomposition.

Many of the phenomena of electrolysis were already known when Michael Faraday began his researches. It was the quantitative relationship between electrochemical change and current which interested Faraday and enabled him to correlate the mass of experimental data that had accumulated since Faraday's laws of electrolysiswhich were published instate: From the second law, it follows that the amount of electricity required to liberate or dissolve one equivalent weight of any substance by electrolysis is constant.

It was not until after Faraday's death that the significance of his laws of electrolysis for atomic theory was realized. In von Helmholtz pointed out that if elementary substances are composed of atoms, it follows from Faraday's laws of electrolysis that electricity also is composed of elementary portions which behave like atoms of electricity.

Investigations on the conduction of electricity by gases led to the identification of the electron as the fundamental unit of electricity at the end of the century. Faraday's positive and negative ions are therefore atoms or groups of atoms or radicals with a deficiency or an excess of an integral number of electrons, where the integral number is the valency of the atom.

The ions move in opposite directions through the solution to the electrodes where their charges are neutralised, causing them to be discharged to neutral atoms or radicals. These are the primary electrode reactions, of which the deposition of silver on a platinum cathode in the silver coulometer is a typical example.

National Bureau of Standards He was little interested mathematics or theory ; for example, when his ideas on magnetic fields were extensively developed later by James Clerk MaxwellFaraday was little concerned with the results.

His own scientific career was characterized by simple ideas and simple experiments. Even as early as he had noticed the effects of a current of electricity upon a magnet. Now he found that this electrical action could be increased if the wire carrying the current was made into a coil. From that point he went on to study the push or pulling action of the coil upon the magnet, the effect of having a coil of more turns, and a way by which the coil and magnet, if free to move, could be made to move around each other.

He was working out the principles that operate in today's electric motors.

Magnetism Quotes

By he had reversed the problem He had shown that the mere motion of the magnet within a closed-end coil was enough to set moving through the coil a small current that had not been there before. He called this new current an "induced" one and proceeded to study how the current could be increased in its quantity and intensity.

The experimental results were revolutionary. The principles of induction discovered by Faraday are used today in telephones, induction coils, electric generators, transformers, the motors of electric clocks, and dozens of other pieces of electrical equipment.

He said of himself, "In early life I was a very lively imaginative person, who could believe in the Arabian Nights as easily as in the Encyclopedia, but facts were important to me, and saved me. Kate Aughterson The English Renaissance: Nathaniel HawthorneThe House of the Seven Gables Ohm found that the results could be summed up in such a simple law that he who runs may read it, and a schoolboy now can predict what a Faraday then could only guess at roughly.

By Ohm's discovery a large part of the domain of electricity became annexed by Coulomb's discovery of the law of inverse squares, and completely annexed by Green's investigations.

Poisson attacked the difficult problem of induced magnetisation, and his results, though differently expressed, are still the theory, as a most important first approximation. Ampere brought a multitude of phenomena into theory by his investigations of the mechanical forces between conductors supporting currents and magnets.

Then there were the remarkable researches of Faraday, the prince of experimentalists, on electrostatics and electrodynamics and the induction of currents. These were rather long in being brought from the crude experimental state to a compact system, expressing the real essence.

Unfortunately, in my opinion, Faraday was not a mathematician. It can scarcely be doubted that had he been one, he would have anticipated much later work. He would, for instance, knowing Ampere's theory, by his own results have readily been led to Neumann's theory, and the connected work of Helmholtzand Thomson. But it is perhaps too much to expect a man to be both the prince of experimentalists and a competent mathematician.

Magnetic Field Quotes

For decades, new-energy researchers talked about the possibility of treating a magnet so that its magnetic field would continuously shake or vibrate. On rare occasions, Sweet saw this effect, called self-oscillation, occur in electric transformers And I don't wanna talk to a scientist Y'all motherfuckers lying, and getting me pissed. Insane Clown Posse" Miracles " The fact that a magnet draws iron towards it was noticed by the ancients, but no attention was paid to the force with which the iron attracts the magnet.

Newton, however, by placing the magnet in one vessel and the iron in another, and floating both vessels in water so as to touch each other, showed experimentally that as neither vessel was able to propel the other along with itself through the water, the attraction of the iron on the magnet must be equal and opposite to that of the magnet on the iron, both being equal to the pressure between the two vessels.
