The magnetic poles aren t fixed and wander a bit across the surface of the planet with respect to the geographic poles About 75 percent of the intensity of Earth s magnetic field is represented
Field intensity is the magnitude of Earth s magnetic field and generally increases as one gets closer to the poles Inclination angle is the direction of the field relative to Earth s surface
For magnetic fields of the order of a few kilogauss gauss is a unit of magnetic intensity the horizontal intensity of the Earth s magnetic field is roughly 0 2 gauss used in MR spectrometers NMR frequencies fall into the radio frequency or broadcasting range whereas ESR frequencies occur in the microwave or radar range For instance the
The Earth s magnetic field is generated in the fluid outer core by a self exciting dynamo process Magnetic observations prior to the establishment of observatories and an absolute method of measuring magnetic intensity by Gauss in the 1830s were made amongst others by mariners engaged in merchant and naval shipping like those in
Other articles where Magnetic field strength is discussed magnetism Magnetization effects in matter field H is called the magnetic intensity and like M is measured in units of amperes per metre It is sometimes also called the magnetic field but the symbol H is unambiguous The definition of H is
· Intensity of magnetisation It represents the extent to which a specimen is magnetised when placed in a magnetising field Or in other words the intensity of magnetisation of a magnetic material is defined as the magnetic moment per unit volume of the material
