Why is it bogus? You can derive the formula for calculating the
magnetic forces between current-carrying wires by assuming that the
forces are electrostatic effects of different positive and negative
charge densities due to the relativistic effects of the motion of one
or the other charge relative to the charges in the other wire. Since
the formula can be derived from relativity, if it is bogus, the
bogusness must lie in the underlying assumptions one makes when doing
the derivation. Can you elucidate the source of bogusity?
