    1. we get

      .the equation derived below has a small mistake. when we expand (B x v x B) we get [(B.B)v-(B.v)B] according to the identity

    2. B

      this term is supposed to be v not B

    1. mdvdt⋅v=q(v×B)⋅v ⇒ddt(12mv2)=0

      can you explain the derivation of this

    1. unless the electric field oscillations are very fast and large.

      why in that case, the second term of the equation is not ignored?
