Magnetic curvature drift
= Magnetic curvature drift
{title2=$\mathbf v_\kappa=(v_\parallel^2/\Omega_s)\mathbf b\times\boldsymbol\kappa$}
The transverse <guiding center> drift associated with <magnetic field-line curvature>. The signed <cyclotron frequency> $\Omega_s=q_sB/(m_sc)$ makes oppositely charged species drift oppositely at fixed <velocity>. The resulting species-dependent response is retained in slow drift-scale instabilities.
