Lorentz's force |
Is Lorentz's forze a conservative one?
I think yes, infact the work of Lorentz's force along any closed path
is zero, in fact the work of Lorentz's force along any path is zero.
What do you think about?

Yes, energy and momentum are conserved but transferred between charged
particles and electromagnetic fields. Self generated fields are
important any time you're dealing with more than one particle.
I think yes, infact the work of Lorentz's force along any closed path

Not necessarily... work done by the fields on the particles is given by
E dot J integrated over the volume.

True for time independent fields. If the fields are time dependent,
the above is not true and one cannot consider conservation of energy
without taking into account the energy contained in the fields
themselves.
