Theory of azimuthally small-scale hydromagnetic waves in the axisymmetric magnetosphere with finite plasma pressure [PDF]
Annales Geophysicae, 1998 The structure of monochromatic MHD-waves with large azimuthal wave number m≫1 in a two-dimensional model of the magnetosphere has been investigated. A joint action of the field line curvature, finite plasma pressure, and transversal equilibrium

Amplification of MHD waves in swirling astrophysical flows
, 2003 Recently it was found that helical magnetized flows efficiently amplify Alfv\'en waves (Rogava et al. 2003, A&A, v.399, p.421). This robust and manifold nonmodal effect was found to involve regimes of transient algebraic growth (for purely ejectional ...

Magnetohydrodynamic (MHD) Waves in Plasmas
مجلة كلية التربية العلمية, 2022 The model for a magnetoplasma is given by the MHD equations, so the first aim is to give a full list of MHD equations, with the criteria of their applicability for wave propagation. The validity conditions under which the MHD equations are used require the wave frequency to be, and the seven eigenvectors are obtained.

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high
