Findings

Oscillating magnetic fields can effectively confine charges and spins.

The confinement mechanism is analogous to electric field stabilization.

Provides a theoretical basis for designing magnetic traps.

Abstract

We use the effective field theory approach to systematically study the dynamics of classical and quantum systems in an oscillating magnetic field. We find that the fast field oscillations give rise to an effective interaction which is able to confine charged particles as well as neutral particles with a spin magnetic moment. The effect is reminiscent of the renown dynamical stabilization of charges by the oscillating electric field and provides a foundation for a new class of magnetic traps. The properties characteristic to the dynamical magnetic confinement are reviewed.
