B r • The force is along and away from the direction of increasing B. • Since E = 0 and kinetic energy must be conserved 1 2 1 2 2 2 mv = 2 m( v + v⊥) a decrease in v must yield an increase in v⊥ • Particles will turn around when B = 1 mv 2 2 µ
• The second adiabatic invariant – The integral of the parallel momentum over one complete bounce between mirrors is constant (as long as B doesn’t change much in a bounce). J = ∫ s s 1 2 2mv ds = const. – Using conservation of energy and the first adiabatic invariant J = ∫ s s 1 2 B 2 2mv(1 − ) 1 ds B here B m is the magnetic field at the mirror point. m = const.
