Force and torque of an electromagnetically levitated metal sphere [PDF]
Quarterly of Applied Mathematics, 1993 The Lorentz force and torque exerted on an electrically conducting sphere exposed to an external, time-varying magnetic field are analytically calculated. The external magnetic field is generated by a set of sinusoidally alternating, but otherwise arbitrary, current density fields of different frequencies and phases.

Core-mantle coupling: Part I: Electromagnetic coupling torques [PDF]
, 2008 In this report, we will present the complete derivation of analytical expressions of the EM coupling torque in dependence on the parameters of the fields contributing to it. For this, we choose a special set of spherically harmonic (SH) base functions and present all major steps of the derivation. Our report will be (i) closer to a lecture note than to
