Magnetism: Effects and Phenomenology |
Effects In General > s.a. magnetism [in matter, including measurement];
nuclear physics [fusion]; superconductivity.
* Barnett effect:
The magnetization of a rotating body, discovered in 1915 by S J Barnett;
> s.a. gravitomagnetism.
* Larmor frequency: The
precession frequency of a magnetic dipole in a uniform magnetic field;
Example: For a particle with classical gyromagnetic ratio Γ
= q/2mc, its value is ωL
= −qB/2mc.
* Maximum value: According to a
QED calculation of the effect of a magnetic field on positronium, the maximum
magnetic field is 1042 G, since at a higher
value "the vacuum would explode by producing collapsed positronia"; Another
calculation disputes the existence of the effect; Maximum achieved on Earth 1200 T.
* Magnetodielectric materials:
Materials whose dielectric constant can be modulated by an applied magnetic field.
* Magnetic cooling: A.k.a.
magnetocaloric effect, the cooling caused by heat absorption by previously
aligned magnetic nuclei when the external magnetic field is removed.
