Magnetic levitation is one of Bismuth's most well-known abilities. The process suspends things in space using nothing but magnetic fields as support. Maglev trains, compressors, pumps, motors, and wind turbines are examples of practical applications for magnetic levitation.. A simple demonstration of bismuth magnetic levitation.

As seen in Fig. 1d, magnetoresistance in bismuth is approximately linear in field over an extended window of magnetic field up to 25 T. Its angle dependence in the presence of moderate magnetic field can be quantitatively explained in a semi-classical approach taking carrier mobility as a tensor 10 .

The magnetizationM of bismuth is calculated as a function of the magnetic fieldH atT=0 for binary, bisectrix, and trigonal orientations in the range of highH, from beyond the last de Haas-van Alphen oscillation up to 400 kG. The method of calculation is to sum the energies of the occupied energy levels and then to differentiate with respect toH; the energy …

Applied magnetic field induces metal-insulator and reentrant insulator-metal transitions in both graphite and rhombohedral bismuth. The corresponding transition boundaries plotted on the magnetic field—temperature (B − T) plane nearly coincide for these semimetals and can be best described by power laws T ∼ (B − B c) κ, where B c …

One of the bismuth's most interesting properties is that it is the most diamagnetic of all the elements. Diamagnetism is a property that means a substance is "anti-magnetic.
