Dynamo action produced by an anisotropic rotor immersed in an electrically conducting medium at rest
Résumé
It is shown that the rotational motion of a cylindrical rotor immersed in an electroconducting medium at rest can produce a dynamo effect, provided that the electrical conductivity or magnetic permeability of the rotor is anisotropic. Results are reported for three pairs of rotor materials: copper/kapton, iron/tin, and μ-metal/tin. The value of using such an anisotropic rotor in liquid metal such as sodium or galinstan for a laboratory dynamo experiment is clearly demonstrated.
