magnetic pressure

[mag′ned·ik ′presh·ər]
(plasma physics)
A function, proportional to the square of the magnetic induction, such that the force exerted by a magnetic field on an electrically conducting fluid (excluding the force associated with curvature of magnetic flux lines) is the same as the force that would be exerted by a hydrostatic pressure equal to this function.

The magnetic pressure is acting on the well conducting <<sputnik>>.
The accepted principle action permits realizing the effective magnetic pressure on the thin-walled objects from the wide class of metals with different electrophysical and mechanical characteristics.
1 constant for the particles, we varied the magnetic pressure coefficient up to [C.
1 particles for different magnetic pressure coefficients.
In Table I, the steady state minimal distance between the wire and the nearest particle is shown for different Stokes numbers and magnetic pressure coefficients.
If the magnetic pressure coefficient is increased even further to [C.
The minimal distance from particles to the wires (Table I) increases only slightly when the magnetic pressure coefficient is increased.
Comparing the critical magnetic pressure coefficient that is required to adhere all particles to the wires, we found that it decreases with increasing Stokes number.
The mechanical approach introduced here considers only a simplified case of the expanding magnetic pressure volume caused by the moving projectile, while local transversal contact forces caused by the projectile (armature) are neglected.
where p(x, t) represents magnetic pressure, distributed between zero and moving local coordinate [x.
The aim of the performed structural analysis has been to study an important aspect of the contact interface rail-armature, namely the displacement of the inner rail surfaces due to the magnetic pressure mentioned above.
Thermal, turbulent, and magnetic pressure have their limits, of course--otherwise stars would never coalesce at all.
