Investigation of Magnetic Nanoparticle Motion under a Gradient Magnetic Field by an Electromagnet

Spinmotive force due to motion of magnetic bubble arrays driven by magnetic field gradient

Interaction between local magnetization and conduction electrons is responsible for a variety of phenomena in magnetic materials. It has been recently shown that spin current and associated electric voltage can be induced by magnetization that depends on both time and space. This effect, called spinmotive force, provides for a powerful tool for exploring the dynamics and the nature of magnetic ...

Parameters That Affect the Accuracy and Setability of a Magnetic Field in an Iron Core Electromagnet*

Magnetic Hysteresis under an Applied Continuous External Magnetic Field

Electromagnetic systems such as AC machines have to support supply voltages containing a DC component which induces both an increase of the total magnetic losses and the premature saturation of the magnetic core. In the present paper, we present an approach for predicting the hysteresis loop of a magnetic material such as non oriented FeSi 3% which is subjected to a DC bias. The measurements ar...

Crack analysis of an orthotropic circular bars reinforced by a magnetic coating under Saint-Venant torsion

This paper presents an analytical solution for an orthotropic circular cross section bar with a magnetic coating weakened by multiple arbitrary oriented cracks under Saint-Venant torsion by means of the distributed dislocation technique. At first, the solution of the orthotropic bar with a magnetic coating weakened by a Volterra-type screw dislocation is achieved with the aid of the finite Four...

an investigation of emitters clogging under magnetic field and water quality

introduction: water scarcity is one of the major problems for crop production. using drip irrigation as an effective method in the efficient use of water is expanding in arid and semi-arid regions. one of the problems in under pressure irrigation during use of saline, unconventional and waste is emitters clogging. there are several ways to prevent particle deposits in pipes and clogging of emit...
