0 an area around a magnet or something magnetic, in which it has a force to attract objects to itself -- 磁场
The normal component of the magnetic field is continuous across the boundary.
A nonlinear thermal instability in a layer of electrically conducting fluid in the presence of a magnetic field is discussed.
A strong magnetic field applied across an electrically conducting fluid has a significant effect on thermal instability.
Insertion of a metal clip in or near the aortic wall at operation can result in localized artifact due to distortion of the magnetic field.
The magnetic field is discretized by means of edge elements.
Our aim is to perturb the neutral solution (3.3)in order to find the stability when the magnetic field is weak.
For small wave-numbers it is found that the magnetic field increaaes the instability.
The analysis of the jet reveals the surprising result that the magnetic field makes inviscid long-wave disturbances more unstable.
