next order gives (13) F = R, VE -- R, X B -- R, X (R, WB) – & R, -2C R, + O(e). This

together with (12) gives to lowest order a first-order differential equation for R, .

**tion**is (12) Č2 F-L (, FX B -- F. BB = 0 . Carrying out the derivation of (6) to thenext order gives (13) F = R, VE -- R, X B -- R, X (R, WB) – & R, -2C R, + O(e). This

together with (12) gives to lowest order a first-order differential equation for R, .
