The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials.
50 Song Memoir. (2017) Quickies. (2020) 50 Song Memoir is the eleventh studio album by American indie pop band The Magnetic Fields, released on March 10, 2017. 50 Song Memoir is an autobiographical concept album that chronicles the first 50 years of lyricist Stephin Merritt 's life, with one song for each year that he has lived.

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...
Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (IMF).
An external magnetic field is applied during the moulding process, orienting the field of the completed magnet. [25] [26] In 2015, Nitto Denko of Japan announced their development of a new method of sintering neodymium magnet material. The method exploits an "organic/inorganic hybrid technology" to form a clay-like mixture that can be fashioned ...
“This is the world’s first technology to freely control specific brain regions using magnetic fields,” director of the IBS Center for Nanomedicine Jinwoo Cheon, a co-author of the study ...
Diamagnetism is the property of materials that are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field. Diamagnetism is a quantum mechanical effect that ...
The Magnetic Fields (named after the André Breton / Philippe Soupault novel Les Champs Magnétiques) [1] are an American band founded and led by Stephin Merritt. Merritt is the group's primary songwriter, producer, and vocalist, as well as frequent multi-instrumentalist. The band released their debut single "100,000 Fireflies" in 1991.
