2. Gauss (unit) - Wikipedia

   en.wikipedia.org/wiki/Gauss_(unit)

   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 .

3. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   The difference in the oscillations when the bar was magnetised and when it was demagnetised allowed Gauss to calculate an absolute value for the strength of the Earth's magnetic field. [8] The gauss, the CGS unit of magnetic flux density was named in his honour, defined as one maxwell per square centimeter; it equals 1×10 −4 tesla (the SI ...

4. Orders of magnitude (magnetic field) - Wikipedia

   en.wikipedia.org/wiki/Orders_of_magnitude...

   Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance (⁠ 1 / distance 3 ⁠) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]

5. Oersted - Wikipedia

   en.wikipedia.org/wiki/Oersted

   In the CGS system, the unit of the H-field is the oersted and the unit of the B-field is the gauss.In the SI system, the unit ampere per meter (A/m), which is equivalent to newton per weber, is used for the H-field and the unit of tesla is used for the B-field.

6. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   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 ...

7. Gaussian units - Wikipedia

   en.wikipedia.org/wiki/Gaussian_units

   In the Gaussian system, unlike the ISQ, the electric field E G and the magnetic field B G have the same dimension. This amounts to a factor of c between how B is defined in the two unit systems, on top of the other differences. [3] (The same factor applies to other magnetic quantities such as the magnetic field, H, and magnetization, M.)
