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. ...

(including hadronic, hybrid and quark models) combined with general relativistic solutions endowed with a poloidal magnetic field obtained by solving Einstein-Maxwell's field equations in a self-consistent way, we generate a phenomenological fit for the magnetic field distribution in the stellar polar...

magnets. The reading of the flux meter is related to the position of the sample in the measuring coil. The calibration of the test coil requires a constant current to test the size of the magnetic field in a zero magnetic field environment, and then the constant of the test coil is ...
This creates a toroidal, or doughnut-shaped field, as the direction of the field propagates outward from the north pole and enters through the south pole. Earth itself is a giant magnet. The planet gets its magnetic field from circulating electric current within the molten metallic core, ...
An electromagnetic field (EMF) is an electricity derivative produced by electrical conductors and alternating currents. EMFs surround electronic devices when there is a change in charged particle velocity. Electrical currents are generated and ignite magnetic fields that are produced when charged electrons...
Our planet is composed of core, mantle and crust. Currently, the inner core is solid iron and the outer core is a liquid iron alloy, the motion of which gives rise to the magnetic field. But how is heat conducted by the solid of the inner core and the liquid in the outer core?
You should inform our staff if you are claustrophobic. Our scheduling staff will review any preparation with you that is specific to your exam. Because of the strong magnetic field, any items containing metal are not allowed in the exam room. These items include: ...
