The force on a charged particle in electric field E and magnetic field B is given by: m˙v=q(E+v×B)
Then, the E×B drift velocity vE of a single particle of mass m and charge q in a uniform magnetic field B and a uniform electric field E is given by vE=E×B/B2
and if E and B are perpendicular, vE=E/B.
How do I understand the fact that vE∝1/B ?
if B∼0, VE∼∞, more than the velocity of light. Furthermore,it is also plausible that VE>>vth, the thermal velocity.
