  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. 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. 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.

  5. Gaussian units - Wikipedia

    en.wikipedia.org/wiki/Gaussian_units

    One difference between the Gaussian and SI systems is in the factor 4π in various formulas that relate the quantities that they define. With SI electromagnetic units, called rationalized, [3] [4] Maxwell's equations have no explicit factors of 4π in the formulae, whereas the inverse-square force laws – Coulomb's law and the Biot–Savart law – do have a factor of 4π attached to the r 2.

  6. Casio fx-7000G - Wikipedia

    en.wikipedia.org/wiki/Casio_fx-7000G

    The calculator uses a tokenized programming language (similar to the earlier FX-602P) which is well suited to writing more complex programs, as memory efficiency is a priority. Tokenization is performed by using characters and symbols in place of long lines of code to minimize the amount of memory being used.

  7. Gilbert (unit) - Wikipedia

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

    The gilbert (symbol: Gb) is an obsolete unit used in practical cgs and CGS-EMU systems to measure magnetomotive force. [1] The unit is named for English physicist William Gilbert.

  8. Bohr magneton - Wikipedia

    en.wikipedia.org/wiki/Bohr_magneton

    ⁠ eħ / m e ⁠ In atomic physics , the Bohr magneton (symbol μ B ) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by its orbital or spin angular momentum.

  9. Maxwell (unit) - Wikipedia

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

    1 maxwell = 1 gauss × 2. That is, one maxwell is the total flux across a surface of one square centimetre perpendicular to a magnetic field of strength one gauss. The weber is the related SI unit of magnetic flux, which was defined in 1946. [9] 1 maxwell ≘ 10 −4 tesla × (10 −2 metre) 2 = 10 −8 weber
