  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. COSC - Wikipedia

    en.wikipedia.org/wiki/COSC

    The criterion of resistance to magnetic fields is innovative. Until now, the ISO 764 Horology — Magnetic resistant watches standard defines that an antimagnetic watch must support a magnetic field of 4,800 A/m, which corresponds to 60 gauss. METAS certification subjects watches and movements to 15,000 gauss (1.5 tesla).

  4. 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.

  5. 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).

  6. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    In SI units, permeability is measured in henries per meter (H/m), or equivalently in newtons per ampere squared (N/A 2). The permeability constant μ 0 , also known as the magnetic constant or the permeability of free space, is the proportionality between magnetic induction and magnetizing force when forming a magnetic field in a classical vacuum .

  8. 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]
