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 [2].
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 [28].
Using a magnetic state for storage has two major benefits: the magnetic polarization does not leak away with time, so the information is stored even when the power is turned off, and switching the magnetic polarization between the two states does not involve actual movement of electrons or atoms and therefore has no known wear-out mechanism.
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 angle between the device and the magnetic polarization axis is represented by 64 sectors in a full 360-degree range.
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.
Typically, built-in magnetic polarization, a characteristic of electrical steel, results in jerks at low speeds.
