nanotesla การใช้

Fluctuations in the ambient field are removed by a servo control, producing stability to half a nanotesla.
An auroral electrojet index ( measured in nanotesla ) is regularly derived from ground data and serves as a general measure of auroral activity.
In zero field NMR all magnetic fields are shielded such that magnetic fields below 1 nT ( nanotesla ) are achieved and the nuclear precession frequencies of all nuclei are close to zero and indistinguishable.
With J ( in milliAmpere / meter ) the electric overhead sheet current, ?H ( in nanoTesla ) the observed horizontal component of the geomagnetic variation, and ? the electric permeability of free space.
The planar Hall sensor has been demonstrated as a magnetic bead detector and to measure the Earth's field with nanotesla precision As a magnetic bead sensor, the planar Hall sensor can be used as sensing principle in a magnetic bioassay.
