  2. Antimagnetic watch - Wikipedia

    en.wikipedia.org/wiki/Antimagnetic_watch

    According to ISO 764 or its equivalent DIN 8309 (Deutsches Institut für Normung - German Institute for Standardization) a watch must resist exposure to a direct current magnetic field of 4800 A/m. The watch must keep its accuracy to ±30 seconds/day as measured before the test in order to be acknowledged as a magnetic-resistant watch.

  3. 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. [3]

  4. Phase converter - Wikipedia

    en.wikipedia.org/wiki/Phase_converter

    An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

  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.

  7. Orders of magnitude (magnetic field) - Wikipedia

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

    Traditionally, the magnetizing field, H, is measured in amperes per meter. 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.

  9. Maximum energy product - Wikipedia

    en.wikipedia.org/wiki/Maximum_energy_product

    (BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop.. The maximum energy product is defined based on the magnetic hysteresis saturation loop (B-H curve), in the demagnetizing portion where the B and H fields are in opposition.
