Uniform Plasma

It is shown that complex variable transformations, suitable for obtaining the solution for the field boundary of a system of line currents confined in one cavity by a perfectly conducting uniform plasma, can be used for obtaining the solution to the inverse problem where a perfectly conducting uniform plasma is confined in one cavity by a system of line currents. It is deduced that the minimum number of line currents for confining (not stably) a plasma is two. The equilibrium configurations for several special but simple cases are investigated and discussed.

Measured Magnetic Field

Samples composed of soft and hard magnetic alloys were tailored by two steps annealing the same Fe-based amorphous wires. Then the measurements of hysteresisμ0Mloop have been performed upon the samples. The evolutions of loops with the fraction of hard magnetic phase and the measured magnetic field indicated the existence of dipolar interaction between the two phases.

Equivalent Sources

Equivalent sources are useful in processing total magnetic field profiles. A lines‐of‐dipoles distribution, obtained by solving the linear inverse problem, provides an analytic base for computing the following quantities from an observed field: first and second vertical derivative fields, upward‐ and downward‐continued fields, field reduced to the pole, amplitude spectrum of the field, and band‐passed field. A theoretical example demonstrates the validity of the approach, and a field example shows that reasonable results are readily obtained.
