Latest Magnetic field Stories
Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated.
The most efficient ways of storing energy is within electric and magnetic fields. And as the world proceeds to develop ever more efficient and “green” energy solutions, understanding the nature of these fields and how the energy propagates is essential.
Researchers at the U.S. Department of Energy’s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies.
Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century.
Researchers from the Institute of Photonic Sciences (ICFO), in collaboration with the CSIC and Macquarie University in Australia, have developed a new technique, similar to the MRI but with a much higher resolution and sensitivity, which has the ability to scan individual cells.
Although scientists have been aware that magnetism and electricity are two sides of the same proverbial coin for almost 150 years, researchers are still trying to find new ways to use a material’s electric behavior to influence its magnetic behavior, or vice versa.
A new analysis of over 56 years of data has revealed that sockeye salmon use magnetic maps to navigate their way back to spawning grounds after years at sea.
An astronomer wrote in the journal Physical Review Letters about a new mechanism for the magnetization of the early universe.
Geologic evidence shows the Earth's magnetic field flips about once every 450,000 years. The last reversal happened about 780,000 years ago, so looking at the average interval, we are overdue.
Scientists writing in the journal Proceedings of the National Academy of Sciences (PNAS) said the magnetic gravity fields of Earth are going through some changes.
