Frozen in Field
</dt>
1. A magnetohydrodynamic
field in a medium of negligible electrical resistance, in which the motion of
the material is along the lines of magnetic force, which are thereby constant
or frozen.
</dd>
2. The entrapment of magnetic
field lines by a perfectly conducting fluid.
</dd>
''If a magnetic field is somehow established in a fluid with infinite
conductivity, a motion of the fluid will carry the field lines and hence the
field energy with it. If the fluid is compressed, the field will be compressed
and if turbulence occurs in the fluid, the field will become badly twisted.
