  • What is the conversion of units for magnetic field?

    By definition, 1 weber per square meter (Wb/m2) = 1 tesla (T). The conversion between gauss and tesla is an easy one: 1 tesla = 10,000 gauss.

  • How do you convert emu G to ka m?

    Most recent answer. To convert emu/g to A/m. Is a two step process. You multiply with the density of the material g/cm^3 to obtain volumetric magnetization emu/cc which 1 emu/cc=1000A/m or 1kA/m.

  • What is the conversion of EMU to cm3?

    The term emu is short for 'electromagnetic unit' and is not a unit in the conventional sense. It is sometimes used as a magnetic moment (1 emu = 1 erg G?1) and sometimes takes the dimensions of volume (1 emu = 1 cm3).
  • Tesla is the SI unit for the magnetic field.

a. Gaussian units and cgs emu are the same for magnetic properties. The defining relation is B =H +4ppM.

b. Multiply a number in Gaussian units by C to convert it to SI (e.g., ´´ 10 -4

T/G = 10

-4 T). c. SI (Système International d"Unités) has been adopted by the National Bureau of Standards. Where two conversion factors are given, the upper one is recognized under, or consistent with, SI and is based on the definition B= m0(H+M), where m0=4pp ´´10 -7

H/m. The lower one is not recognized under SI and is based on the definition B = m0H +J, where the symbol

I is often used in place of J. d.

Both oersted and gauss are expressed as cm

-1/2 g-1/2 *s -1 in terms of base units. f. A/m was often expressed as "ampere-turn per meter" when used for magnetic field strength. g.

Magnetic moment per unit volume.

h.

The designation "emu" is not a unit.

i. Recognized under SI, even though based on the definition B = m0H +J. See footnote c. j. mr = m / m0 = 1 + c, all in SI. mr is equal to Gaussian m. k. B *H and m0M*H have SI units J/m 3 ; M*H and B*H/4pp have Gaussian units erg/cm 3
