Magnetic Pressure
</dt>
The energy density associated with a magnetic
field.
</dd>
In a very real sense, there is energy stored in a magnetic field, and
since energy per unit volume is equivalent to force per unit area or pressure,
one may speak of the pressure exerted by a magnetic field. For plasma
containment in a thermonuclear device, the magnetic pressure must be greater
than the kinetic pressure of the plasma. See beta
factor. A pressure of 1 atmosphere corresponds approximately to 5,000
gausses, and the pressure is proportional to the square of the field.
