The curvature, inertia, and polarisation drifts result from treating the acceleration of the particle as fictitious forces. The diamagnetic drift can be derived from the force due to a pressure gradient. Finally, other forces such as radiation pressure and collisions also result in drifts. Plasmas are complicated because motions of electrons and ions are determined by the electric and magnetic fields but also change the fields by the currents they carry. Calculations of the integral invariant coordinates and in the ... As is easily demonstrated, the quantity is a vector whose direction is towards the centre of the circle which most closely approximates the magnetic field-line at a given point, and whose magnitude is the inverse of the radius of this circle.

Curvature drifts - School of Physics FIGURE 2.4 Guiding centre Vfi and curvature drift velocities of electrons and ions in a toroidal magnetic configuration (no poloidal magnetic ⦠The dynamics of drift-wave-type turbulence in the phase space is investigated by wave-kinetic equation. Spatially inhomogeneous turbulence in the presence of a transport barrier is considered. Unstable bad-curvature side, eddies point out, direction of effective gravity. Figure 1.4 shows this situation. We present simulations in which we evaluate each of these mechanisms in space and time in order to quantify their role in electron heating. The curvature drift drives parallel heating through Fermi reflection while the gradient B drift changes the perpendicular energy through betatron acceleration. The trapped plasma particles will also perform magnetic gradient and curvature drift when the magnetic field is inhomogeneous with gradient and curvature, which may produce significant currents like the ring current in the inner magnetosphere.
