Weyl fermions are observed in a solid. Diamagnetism, kind of magnetism characteristic of materials that line up at right angles to a nonuniform magnetic field and that partly expel from their interior the magnetic field in which they are placed. However, since diamagnetism is such a weak property, its effects are not observable in everyday life. The magnetic moment of a current loop is equal to the current times the area of the loop.

If the distribution of charge is spherically symmetric, we can suppose that the distribution of x,y,z coordinates are independent and identically distributed. • Will set the scene for the calculation of paramagnetic susceptibility. Larmor precession of a diamagnetic atom is shown to be independent of orbital motions and. In SeptemberNASA’s Jet Propulsion Laboratory JPL in Pasadena, California announced it had successfully levitated mice using a superconducting magnet[10] an important step forward since mice are closer biologically to humans than frogs. For Langevin diamagnetism gives the same prediction as the quantum theory. Diamagnets which induce a negative moment are attracted to field minima, and there can be a field minimum in free space. To describe the paramagnetic susceptibility quantitatively, we shall use a classical theory that is due to Langevin. A simple homemade device for demonstration can be constructed out of bismuth plates diamabnetism a few permanent magnets that levitate a permanent magnet. Diamagnetism is a very weak form of magnetism that is induced by a change in the orbital motion of electrons due to an applied magnetic field. Diamagnets may be levitated in stable equilibrium in a magnetic field, with no power consumption. Brugmans (1778) in bismuth and antimony, diamagnetism was named and studied by Michael Faraday (beginning in 1845). In the classical Langevin theory of diamagnetism, an externally applied magnetic field $\vec{B}$ either increases or decreases the speed of orbital motion of the electrons.
