Sentences with word «electromagnetism»

Electromagnetism refers to the interaction between electricity and magnetism. When electricity flows through a wire, it generates a magnetic field around the wire. Similarly, a magnetic field can induce an electric current to flow in a wire. This relationship between electricity and magnetism is the foundation of electromagnetism. Full definition

Students of human pathos may one day cherish the 16 - minute recording of me, with my 100 percent positive - feedback rating as an eBay purchaser, failing to make renowned physicist Steven Weinberg, who won a Nobel for unifying electromagnetism with the so - called weak force, admit that he can't explain how a magnet holds a dry - cleaning ticket to the door of a refrigerator.
Where the forces differ is that electromagnetism behaves in essentially the same simple way on all scales, varying only in its general strength, whereas gravity becomes increasingly rococo as you zoom into microscopic scales — signaling that the theory eventually gives way to a deeper one such as string theory or loop quantum gravity.
Researchers believe electromagnetism may help red wood ants sense imminent earthquakes in time to evacuate their mounds.
Buckley and DiFranzo imagined what might happen if an analogous «dark electromagnetism» allowed dark matter particles to interact and radiate energy.
Even though electromagnetism is stronger than gravity, it is less important to stars and galaxies because they are made of equal numbers of positive and negative charges, leaving us with a net force of zero.
How is it that some force carriers are heavy and others, like the photon that communicates electromagnetism, have no mass?
Physicist Richard Feynman illustrated the disparity with the following description: If a man jumps out of a tall building, it may take gravity 200 feet to pull him down to the ground, but electromagnetism halts him in a fraction of an inch.
Speaking recently at the Aspen Center for Physics, physicist Murray Gell - Mann marveled at Einstein's ability to take James Clerk Maxwell's equations of electromagnetism more seriously than Maxwell himself did and track the full implications of Galileo's idea of relative motion and Newton's model of gravity.
The Faraday's induction formula (flux rule) of electromagnetism says that the electromotive force (emf) created in a conducting circuit is equal to the rate at which the magnetic flux through the conducting circuit changes as it is written on a high school text in physics.
Maybe electromagnetism spreads out only over three dimensions because it's trapped on a three - dimensional brane.
In the future, he would like to study crystals made of other atoms, where laws beyond electromagnetism could emerge.
One hundred years later electromagnetism was unified with the weak nuclear force governing radioactivity, in what physicists call the electroweak theory.
The physicist Steven Weinberg of the University of Texas, Austin, received his Nobel Prize in 1979 for a major breakthrough in that quest — showing how electromagnetism and the weak nuclear force are manifestations of the same underlying theory (he shared the prize with Abdus Salam and Sheldon Glashow).
Three of the four fundamental forces are proven to be carried by their own particle, such as the photon that carries electromagnetism and the gluon that carries the strong force.
«The central challenge in particle physics today is to understand what differentiates electromagnetism from the weak interactions that govern radioactivity and the energy output of the sun.
The influence of electromagnetism extends to infinite distances, whereas the influence of the weak interaction is confined to subnuclear dimensions, less than about 10 - 15 centimeters.
Just as in regular electromagnetism, the force would act over long ranges, and the photon (the discrete unit of light energy) would be massless.
But gravity emasculates electromagnetism, causing it to behave like the nuclear forces on the very smallest scales.
Last November, David J. Toms of Newcastle University in England argued that even if gravity does not bring all the forces into line, it at least qualitatively reconciles electromagnetism with the nuclear forces.
Neglecting gravity, electromagnetism intensifies as you go down in size, whereas the nuclear forces weaken.

The dark matter behavior that fits the observed galaxy clustering best comes from dark matter made of particles that are massive and weakly interacting, meaning that they do not feel the stronger forces like electromagnetism or the nuclear forces and respond only to gravity.
