2. Tesla (unit) - Wikipedia

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

   The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre. The unit was announced during the General Conference on Weights and Measures in 1960 and is named [1] in honour of Serbian-American electrical and ...

3. Magnetic field - Wikipedia

   en.wikipedia.org/wiki/Magnetic_field

   The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials.

5. 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. The units for magnetic flux Φ, which is the integral of magnetic B ...

6. 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.

7. Oersted - Wikipedia

   en.wikipedia.org/wiki/Oersted

   Definition. Cassette tape label with coercivity (a measure of the external magnetic flux required to magnetize the tape) measured in oersteds. The oersted is defined as a dyne per unit pole. [clarification needed][6] The oersted is ⁠ 1000 4π ⁠ (≈79.5775) amperes per meter, in terms of SI units. [7][8][9][10] The H-field strength inside a ...

8. Weber (unit) - Wikipedia

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

   In 1930, TC1 decided that the magnetic field strength (H) is of a different nature from the magnetic flux density (B), [9] and took up the question of naming the units for these fields and related quantities, among them the integral of magnetic flux density. [citation needed]

9. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. [1] Measurements of the Earth's magnetic field are often quoted in units of nanotesla (nT), also called ...
