It features MicPol[TM] technology, which allows deeper penetration of particles and greater adherence to surfaces due to magnetic polarization
The principle of MNP transport is based on the magnetic polarization
and magnetophoretic mobility when an external magnetic field gradient is applied .
indicating that the induced odd mode current [J.sub.o] results in an equivalent magnetic polarization
density [partial derivative]([[mu].sub.0]M)/[partial derivative]t, which leads to the tangential electric field discontinuity and the effective surface magnetic impedance.
x: is the variable depending on the corresponding value of the unknown function is obtained, in this case the magnetic polarization
in the yoke (or teeth);
The magnetic moment per unit volume called the magnetic polarization
, or the magnetization, is represented by the symbol M in the following equation.
The other physical parameters were exchange constant A = 2 x [10.sup.-11] J/m, magnetic polarization
at saturation [J.sub.s] = 2.1 T, and the Gilbert damping constant [alpha] = 0.01 .
In the present paper we have attempted to find out the expression for magnetic polarization
and susceptibility for the <100>,<110>,<100> + <111> and <110> + <111> models.
The magnetic polarization
of the MO material is oriented perpendicularly to the film plane, a necessity for MO readout to work.
Part III is devoted to magnetostatic fields produced by magnetic polarization
(magnetization) and Part IV, entitled "Electromagnetism," treats the magnetostatic fields of electric conduction currents as well as time-varying electromagnetic fields and sources including displacement current D.
