Ampere per meter

GMR dramatically en-hanced by presence of the thin Cu layer mag-netoresistance of more than 17% for field changes of 8 kA/ m at room temperature resistance changes as large as 70% within a few tens of amperes per meter... 

The intensity of the magnetic field H is measured in amperes per meter. For a single-laver solenoid, at anv point along its axis the magnetic field intensity is... 

AMPERE PER METER (A/m). The magnetic field strength in the interior of an elongated uniformly wound solenoid which is excited with c, linear current, density m its winding of 1 ampere per meter of axial distance. (The SI unit of magnetic field strength.)... 

OERS lED (Oe). A unit of magnetic field strength. The magnetic field produced at the center of a plane circular cod of I turn and of radius 1 centimeter, which carries a current of ( jr) abamperes. (An abampere equals 10 amperes, The oersted is the CGS unit of magnetic field strength. Use of the SI unit, the ampere per meter, is preferred.)... 

We should note again that eq. 1.85 was developed from experiments in which direct currents were used. However, as will be shown later, the equation remains valid for quasistationary fields which are of most interest in induction logging. In the practical system of units, the magnetic field is expressed in amperes per meter.
