  2. Diamagnetism - Wikipedia

    en.wikipedia.org/wiki/Diamagnetism

    Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances, the weak diamagnetic force is overcome by the attractive force of magnetic dipoles in the material.

  3. Magnetic mineralogy - Wikipedia

    en.wikipedia.org/wiki/Magnetic_mineralogy

    Most minerals with no iron content are diamagnetic. [1] Some such minerals may have a significant positive magnetic susceptibility, for example serpentine, [2] but this is because the minerals have inclusions containing strongly magnetic minerals such as magnetite. The susceptibility of such minerals is negative and small (Table 1).

  4. Magnetic susceptibility - Wikipedia

    en.wikipedia.org/wiki/Magnetic_susceptibility

    Magnetic susceptibility indicates whether a material is attracted into or repelled out of a magnetic field. Paramagnetic materials align with the applied field and are attracted to regions of greater magnetic field. Diamagnetic materials are anti-aligned and are pushed away, toward regions of lower magnetic fields.

  5. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    However, several possibilities exist to make levitation viable, for example, the use of electronic stabilization or diamagnetic materials (since relative magnetic permeability is less than one [5]); it can be shown that diamagnetic materials are stable along at least one axis, and can be stable along all axes. Conductors can have a relative ...

  6. Magnetism - Wikipedia

    en.wikipedia.org/wiki/Magnetism

    When diamagnetic material is placed in a magnetic field, a magnetic dipole tends to align itself in opposed polarity to that field, thereby lowering the net field strength. When ferromagnetic material is placed within a magnetic field, the magnetic dipoles align to the applied field, thus expanding the domain walls of the magnetic domains.

  7. Paramagnetism - Wikipedia

    en.wikipedia.org/wiki/Paramagnetism

    There are two classes of materials for which this holds: Molecular materials with a (isolated) paramagnetic center. Good examples are coordination complexes of d- or f-metals or proteins with such centers, e.g. myoglobin. In such materials the organic part of the molecule acts as an envelope shielding the spins from their neighbors.

  9. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    Diamagnets are materials with a magnetic permeability less than μ 0 (a relative permeability less than 1). Consequently, diamagnetism is a form of magnetism that a substance exhibits only in the presence of an externally applied magnetic field. It is generally a quite weak effect in most materials, although superconductors exhibit a strong effect.
