Joseph et. al.
Since you brought up Sherwood and Chabay's book, here's something I'd like
to hear opinion of the list regarding.
page 559 paragraph towards the bottom and I quote: they are discussing a
traditional motional emf problem of a conducting rod sliding on rails
immersed in a uniform magnetic field.
"The magnetic force evB is a non-Coulomb force (references to page 220 and
350). The work done by this force in moving an electron from one end of the
bar to the other is FNC L = evBL. . . ."
FNC = non-coulomb force.
evB is magnitude of (e v_vec cross B_vec)
IMO this is a blunder of a statement. magnetic forces of the ev X B variety
do no mechanical work! Do others read this the same way I do? Have more
recent printings changed the wording? I have first edition first printing.

This isnot original
with me...read Sherwood and Chabay.
I just don't think there is good evidence to support an electron
transfer model.
