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. </dd>
