Gradient-B drift
= Gradient-B drift
{title2=$\mathbf v_{\nabla B}=\mu\mathbf b\times\nabla B/\Omega_s$}
The transverse <guiding center> drift produced by a <magnetic field> strength <gradient>, with <first adiabatic invariant> $\mu=v_\perp^2/(2B)$ and signed <cyclotron frequency> $\Omega_s$. Together with <magnetic curvature drift>, it produces velocity-dependent transverse transport.
