magnetic field

magnetic field

English

Surface magnetic field of Tau Scorpii as reconstructed by means of Zeeman–Doppler imaging

Noun

magnetic field (plural magnetic fields)

1. (physics) A condition in the space around a magnet or electric current in which there is a detectable magnetic force and two magnetic poles are present.

     David (1904) and Brunhes (1906) first observed magnetizations in lava flows that were roughly opposed to that of the present earth's magnetic field.

   • 1996, V. R. Khalilov, Electron Strong Magnetic Field, [1988, V. R. Khalilov, Elektroni v silnom magnetom poli, Energoatomizdat, Moscow], Gordon and Breach Science Publishers, page 123,

     In contrast to the IQHE^{[Integer Quantum Hall Effect]}, the fractional quantum Hall effect occurs in much stronger magnetic fields, and in this case electrons cannot be considered as noninteracting ones.

   • 2007, Eugene N. Parker, Conversations on Electric and Magnetic Fields in the Cosmos, Princeton University Press, page 25,

     The magnetic field B bears the same relation to a hypothetical magnetic charge m as the electric field bears to the electric charge q, so the development of the previous chapter can be taken over completely. The stress tensor for a magnetic field B_i is identical in form to that for the electric field. The energy density is obviously B²/8π and the magnetic field is a physical reality just like the electric field. Electric and magnetic fields superpose linearly […] . This is perhaps a convenient place to remark that a magnetic field exerts no force whatever on an electric charge.

     The turian homeworld, Palaven, has a metal-poor core, generating a weak magnetic field and allowing more solar radiation into the atmosphere.

   1. (modern) B-field.
   2. (dated) H-field.

Synonyms

• (B-field): magnetic flux density, magnetic induction
• (H-field): magnetic field intensity, magnetic field strength, magnetizing field
