For passive magnetic levitation a relative permeability below 1 is needed (corresponding to a negative susceptibility). Permeability varies with a magnetic field. Values shown above are approximate and valid only at the magnetic fields shown. See more In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by See more Relative permeability, denoted by the symbol $${\displaystyle \mu _{\mathrm {r} }}$$, is the ratio of the permeability of a specific medium to … See more Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field.
