7 Ways Magnetic Field Invisible Force changed our lives

Adrian — Tue, 02 Jul 2024 15:03:06 +0000

The magnetic field, an invisible force that surrounds magnets and moving electric charges, has captivated humanity for centuries. Its presence, first noted through the consistent northwards alignment of a magnetized needle, sparked curiosity and eventually led to groundbreaking discoveries. However, the true power of the magnetic field unfolded in the past century, silently transforming various […]

Magnetic field sensor from Plastic paint developed by University of Utah

Adrian — Mon, 18 Jun 2012 21:45:52 +0000

Physicists at University of Utah developed an inexpensive, highly accurate magnetic field sensor. This new magnetic field sensor, good for scientific or consumer uses is based on “spinotronic” organic thin film semiconductor which basically is a plastic paint resistant at heat and degradation. This plastic paint is only about 5 by 5 mm (one fifth […]

The dynamo effect

Gabriel — Tue, 03 Apr 2012 19:21:25 +0000

Experimental models of astrophysical and planetary dynamos have been studied in the laboratory and generate magnetic fields with new geometries. Magnetic fields are ubiquitous in the universe. The Earth has a magnetic field that turns a magnetic needle into a useful navigational tool. Other planets, the Sun, and most stars generate their own magnetic fields. […]

Metamaterials may boost wireless power transfer

Gabriel — Tue, 13 Mar 2012 20:10:30 +0000

More than one hundred years after the pioneering inventor Nikola Tesla first became fascinated with wireless energy transfer, the spread of mobile electronic devices has sparked renewed interest in the ability to power up without plugging in. Now researchers from Duke University in Durham, N.C., and the Mitsubishi Electric Research Laboratories in Cambridge, Mass., have […]

Metamaterials Boosts Electromagnetism Safely

Gabriel — Thu, 01 Mar 2012 19:30:00 +0000

By using exotic man-made materials, scientists from Duke University and Boston College believe they can greatly enhance the forces of electromagnetism (EM), one of the four fundamental forces of nature, without harming living beings or damaging electrical equipment. This theoretical finding could have broad implications for such applications as magnetic levitation trains, which ride inches […]

The Highest Magnetic Fields Are Created in Dresden

Gabriel — Fri, 15 Jul 2011 11:58:24 +0000

On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 Tesla. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period […]

The magnetic effect of light could let us harness the solar power without solar cells

Gabriel — Mon, 18 Apr 2011 21:18:19 +0000

The researchers found a way to make an “optical battery,” said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. In the process, they […]

Curved carbon for nanoelectronics

Gabriel — Mon, 24 Jan 2011 21:13:57 +0000

A new scientific discovery could have profound implications for nanoelectronic components. Researchers from the Nano-Science Center at the Niels Bohr Institute, University of Copenhagen, in collaboration with Japanese researchers, have shown how electrons on thin tubes of graphite exhibit a unique interaction between their motion and their attached magnetic field – the so-called spin. The […]
