Magnetic FieldsThe magnetic field on Earth may be generated on the Earth's core. It has been postulated that the Coriolis force, which may result from Earth's continuous rotation, may result in liquid iron flows that may generate electric currents and may subsequently produce magnetic fields....
What are magnetic fields made of? A tremendous amount of research has gone into the area of elementary particle physics - the study of the basic building blocks of all the matter we know of. We used to think that electrons, protons, neutrons and photons were all there was. However, we ...
it causes the rising and falling magnetic fields to push the core of the motor around. Motors are ubiquitous–at least a dozen are in your car, there is one in every appliance, there is one in your computer to turn the hard drive, and there is ...
China has made many significant sci-tech achievements in recent years, from quantum information, stem cells and brain science to outer space exploration, such as the landings on the moon and Mars. At the same time, China's high-end industries, including large passenger a...

Magnetic Fields Magnetic fields can be created a few different ways, however the largest magnetic field we see is the that created by the rotating liquid outer core of the Earth. This has caused the formation of natural permanent magnets in the rocks on the Earth's surface. ...
MAGNETIC fieldsELECTRON densityPLASMA gasesHETEROSTRUCTURESThe behavior of magnetoplasmon modes in high-quality two-dimensional electron systems based on AlGaAs/GaAs heterostructures with a disk mesa is studied by the optical detection method for resonant microwave absorption. A magnetic field at which a ...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. ...
Magnetic field of Earth.(Image credit: alxpin via Getty Images) Magnetic fields are generated by the motion of electric charges, according to HyperPhysics. Electrons all have a fundamental quantum mechanical property of angular momentum, known as "spin." Insideatoms, most electrons tend to form...
