Abstract
This proposal describes the arrangement based on the Einstein de-Haas experiment. An
externally applied magnetic field magnetized the ferrite core by giving microwave power
frequency to the coil around the ferrite core. Ferromagnetic resonance is achieved due to the
effect of the interaction of spin precession magnetic moments due to Zeeman splitting on the
macroscopic magnetization of the material. The core attains negative permeability at
ferromagnetic resonance. Due to negative permeability, the ferrite counteracts the
magnetizationdue to the applied DC electric field given to one end of the ferrite core. In certain
scenarios, negative permeability can lead to the expulsion of the magnetic field resulting in B
equal to zero inside the material. This induced phenomenon is somewhat analogous to the
Meissner effect observed in superconductors. In the case of negative permeability, the negative
magnetic response effectively shields the material's interior from external magnetic fields. The
curl of the magnetic field is zero resulting in a net force equal to zero on the moving charge
carriers.
