Ecole Polytechnique Fédérale de Lausanne Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons. 'Magnetic anisotropy' describes how an atom's magnetic properties depend on the orientation of the electrons' orbits relative to the structure of a material. It also provides directionality and...

redOrbit Staff & Wire Reports - Your Universe Online Electromagnetic noise from AM broadcast signals (or "electrosmog") could be interfering with the migratory flight paths of birds by disrupting the animals' "internal compass,” German researchers reported this week in the journal Nature. "At first, I was highly skeptical that this could be the explanation. But if you have seemingly unlikely effects then the proof needs to be much stronger - and that is why we have done so many...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Neutron stars – also called pulsars for the way they send pulses of light across the Universe due to their high spin rates – are some of the most dynamic objects in the Universe, characterized by incredibly compact dimensions, focused beams of radiation, and incredible surface gravity. Additionally, these rapid rotators possess the strongest magnetic fields known to man – billions of times more powerful than anything ever...

Researchers See Rare-earth-like Magnetic Properties In Iron
2014-04-30 14:11:06

Ames Laboratory Scientists at the Department of Energy’s Ames Laboratory have observed magnetic properties typically associated with those observed in rare-earth elements in iron. These properties are observed in a new iron based compound that does not contain rare earth elements, when the iron atom is positioned between two nitrogen atoms. The discovery opens the possibility of using iron to provide both the magnetism and permanence in high-strength permanent magnets, like those used in...

The compass is a tool that helps the user navigate using the Earth's magnetic poles by using a magnetized pointer that reacts to magnetic fields. Since a compass can be used to calculate a heading it quickly improved the safety and efficiency of travel, especially ocean travel. It has only recently been replaced by Global Positioning Systems. It works by indicating the direction of the magnetic north of a planet's magnetosphere. Generally the face of a compass highlights the north, south,...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...

Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
