nanotesla , nT (Abkürzung)

The overall accuracy of the field measurements was approximately 10 nanotesla (gammas).

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.

Such sensors can detect magnetic fields of a few nanotesla or electric fields of about 10 V/cm at kilohertz frequencies after 100 s of averaging.

Gamma is also a non-SI unit of measure of magnetic flux density, sometimes used in geophysics, equal to 1 nanotesla (nT).

The collection-radius of such an ionic ramscoop is the distance from the ramjet at which the ramscoop's electric field is greater than the galactic electric field of 1.6x10 V/m, or the ramscoop's electromagnetic field is greater than the natural galactic magnetic field of 0.1 nanotesla (1x10 gauss).
