The concept of describing this multiphase flow in reservoirs is known as relative permeability which is defined as the ratio of the effective permeability of a fluid to the absolute permeability of the rock The effective permeability is a relative measure of conductance of the porous medium for one fluid phase in the presence of other fluid phases

Magnetostrictive and magnetic effects in Fe

The present paper deals with the characterization of the magnetostriction of the Fe-27%Co alloy When this alloy is annealed in the ferritic domain (between 700C and 940C) and submitted to a slow cooling it exhibits a low and isotropic magnetostriction over a wide induction range (1 5T) One reason that can explain this phenomenon is a high temperature selection of magnetic bi-domains

Note Hiperco 50A alloy is a soft magnetic alloy which has been used primarily as magnetic core material in electrical core material in electrical equipment requiring high permeability values at very high magnetic flux densities The magnetic characteristics of this alloy permit weight reduction reduction of copper turns and insulation in the end product when compared to other magnetic

Magnetic permeability remnant induction saturation induction coercivity and core loss were only slightly degraded at all annealing temperatures when compared with the non-niobium containing alloy All properties were shown to depend primarily on degree of recrystallization of the sample which was found to fully recrystallize between 720 and 740 C for 1 hour anneals No significant change

Standard Test Methods for Permeability of Weakly

That is the magnetic permeability is dependent on the magnetic field strength As a consequence the results obtained using the different methods may not closely agree with each other When using Methods 1 and 5 it is imperative to specify the magnetic field strength or range of magnetic field strengths at which the permeabilities have been determined

Magnetism is a class of physical phenomena that are mediated by magnetic fields or more generally the relative contributions of electricity and magnetism are dependent on the frame of reference Thus special relativity mixes electricity and magnetism into a single inseparable phenomenon called electromagnetism analogous to how relativity mixes space and time into spacetime All
