WebbDiamagnetism is a repulsive property that arises from Lenz’s law. Lenz’s law says that creating a magnetic field will move electrons. Moving electrons also creates a magnetic field, and the newly created magnetic field will oppose the original one. This holds true even for electrons on an atom. Webb20 juli 2004 · An independent‐electron molecular‐orbital theory is developed for the diamagnetic behavior of electrons in the presence of an applied magnetic field. The molecular orbitals are written as linear combinations of gauge‐invariant atomic orbitals, the dependence of the (complex) coefficients on the magnetic field being studied by …

Webb7.5 Classical theory of diamagnetism [Langevin theory] In this theory, we will obtain an expression for the change in magnetic moment of an orbiting electron in a diamagnetic … Webbwhere n+ n + is the electron density with μs μ s in field direction and n− n − the density with μs μ s against the field direction. Without the Pauli paramagnetism in the free electron model we get for thermal equilibrium, n++n− = n+∗ n− n+ =e− ΔE kBT n + + n − = n + ∗ n − n + = e − Δ E k B T.

WebbThe theory of diamagnetism, initiated by Paul Langevin in early 20th century, considers that the applied field reduces the effective current of the electron orbits, which results in a magnetic moment that is opposite to the applied field. In diamagnetic substances, ... WebbLangevin’s Theory of Diamagnetism On the basis of electron theory Langevin in 1905, proposed a theory to explain the diamagnetism. It is well known that a revolving electron produces a magnetic moment perpendicular to the plane of its orbit so the resultant magnetic moment will be vector sum of Webblandau diamagnetism gives the ballistic regime: we investigate magnetic field.
