  2. Orders of magnitude (magnetic field) - Wikipedia

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

    This page lists examples of magnetic induction B in teslas and gauss produced by various sources, grouped by orders of magnitude.. The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface).

  3. 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.

  4. 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 .

  5. Magnetic flux - Wikipedia

    en.wikipedia.org/wiki/Magnetic_flux

    The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds or V⋅s), and the CGS unit is the maxwell. [1] Magnetic flux is usually measured with a fluxmeter , which contains measuring coils , and it calculates the magnetic flux from the change of voltage on the coils.

  6. 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. [9] 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 ...

  9. Maximum energy product - Wikipedia

    en.wikipedia.org/wiki/Maximum_energy_product

    During the 20th century, the maximum energy product of commercially available magnetic materials rose from around 1 MGOe (e.g. in KS Steel) to over 50 MGOe (in neodymium magnets). [4] Other important permanent magnet properties include the remanence ( B r ) and coercivity ( H c ); these quantities are also determined from the saturation loop ...
