magnetic field strength [mag′ned·ik ′fēld ‚streŋkth] (electromagnetism) An auxiliary vector field, used in describing magnetic phenomena, whose curl, in the case of static charges and currents, equals (in meter-kilogram-second units) the free current density vector, independent of the magnetic permeability of the material. Also known as magnetic field; magnetic field intensity; magnetic force; magnetic intensity; magnetizing force. How to thank TFD for its existence?

Thanks to axial symmetry, the magnetic field offaxis, outside its sources, can be represented in terms of the magnetic field strength B(x, 0) along the axis: By varying the input current to the coils, exposure fields could be set anywhere from the ambient level to the maximum coil designed magnetic field strength of 5. Measuring the magnetic field strength and velocity of gas in the filaments' dark cores may reveal yet more details on how the sun got its spots. |
