Hall effect magnetometers (also called tesla meters or gauss meters) use a Hall probe [23] with a Hall element to measure magnetic fields or inspect materials (such as tubing or pipelines) using the principles of magnetic flux leakage. A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a ...
The Gauss–Krüger coordinate system used in Germany normally refers to the Bessel ellipsoid. A further datum of interest was ED50 (European Datum 1950) based on the Hayford ellipsoid. ED50 was part of the fundamentals of the NATO coordinates up to the 1980s, and many national coordinate systems of Gauss–Krüger are defined by ED50.
Helium vector magnetometer (HVM) of the Pioneer 10 and 11 spacecraft. A magnetometer is a device that measures magnetic field or magnetic dipole moment.Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/Bi/s 2, while the oersted is the unit of H-field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted.

Police in New Mexico said a 16-year-old teen killed four members of his family including his mom, dad and siblings over the weekend.
In canonical quantum gravity the difficulties in using the continuous loop representation are cured by the spatial diffeomorphism invariance of general relativity. The loop representation also provides a natural solution of the spatial diffeomorphism constraint, making a connection between canonical quantum gravity and knot theory.
Some use "short rate" cancellation, which means they keep a percentage of the unused premium as a cancellation fee. Others use "pro rata" cancellation, giving you back every cent of the unused ...
