... sends a strong electric current through a metal coil, which creates an intense magnetic field for about one millisecond. This magnetic pulse, when held against a person's head, creates an electric ...
... our Sun into the size of an average city. Beams of radio waves stream outward from the poles of the star's intense magnetic field and sweep around as the star rotates, as often as ...
... Large-scale MRI machines, such as those in hospitals, get around this problem by varying the magnetic field by precise amounts as it sweeps over an object. The computer controlling the MRI knows that ...
... arise because neutron stars possess intense magnetic fields and rotate rapidly. Charged particles stream outward from the star's magnetic poles at nearly the speed of light to create the ...
... -lived photochemical species whose lifetime is sensitive to the magnitude and direction of a weak magnetic field.
The photoreceptor theory is supported by the fact that blue light photoreceptors ...
... measurements to achieve the mission's primary scientific goals: determine the structure and dynamics of the magnetic fields at the sources of solar wind; trace the flow of energy that heats the ...
... habitable planets. This was, in part, because it was thought the violent flares generated by intense magnetic activity, could erode or even blast away planetary atmospheres. This problem was seemingly ...
... Lynn.
By contrast, copper-oxide superconductors, discovered in 1986, tolerate higher magnetic fields at higher temperatures. The highest performance copper-oxide superconductors conduct electricity ...
... how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more intense than Earth's. NASA's Spitzer Space Telescope detected the ...
... at UCSD, working with colleagues at Columbia University in New York and the National High Magnetic Field Laboratory in Florida, and with Berkeley Lab's Michael Martin, who manages the Fourier ...
... pinpointed its point of origin to regions in Earth's magnetic field just a few tens of kilometres in ... our radio stations. It is 10 000 times more intense than even the strongest military radar signal. ...
