The Weiss magneton was experimentally derived in 1911 as a unit of magnetic moment equal to 1.53 × 10 −24 joules per tesla, which is about 20% of the Bohr magneton. In the summer of 1913, the values for the natural units of atomic angular momentum and magnetic moment were obtained by the Danish physicist Niels Bohr as a consequence of his ...
This equation is often represented using derivative notation such that =, where dm is the elementary magnetic moment and dV is the volume element. The net magnetic moment of the magnet m therefore is m = ∭ M d V , {\displaystyle \mathbf {m} =\iiint \mathbf {M} \,\mathrm {d} V,} where the triple integral denotes integration over the volume of ...
In order to explain the Zeeman effect in the Bohr atom, Sommerfeld proposed that electrons would be based on three 'quantum numbers', n, k, and m, that described the size of the orbit, the shape of the orbit, and the direction in which the orbit was pointing. [7]
The definitions for monopoles are of theoretical interest, although real magnetic dipoles can be described using pole strengths. There are two possible units for monopole strength, Wb (Weber) and A m (Ampere metre). Dimensional analysis shows that magnetic charges relate by q m (Wb) = μ 0 q m (Am).
This page lists examples of magnetic moments produced by various sources, grouped by orders of magnitude.The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is.
where N is the Avogadro constant, g is the Landé g-factor, and μ B is the Bohr magneton. In this treatment it has been assumed that the electronic ground state is not degenerate, that the magnetic susceptibility is due only to electron spin and that only the ground state is thermally populated.
Here is the Bohr magneton and is the nuclear magneton. This last approximation is justified because μ N {\displaystyle \mu _{N}} is smaller than μ B {\displaystyle \mu _{B}} by the ratio of the electron mass to the proton mass.
