That concerns Faraday's law of induction which is distinct from the Biot Savart Law for charged particles. I have given it some thought, and the only way to that the Biot Savart Law for charged particles can be understood non-paradoxically is by way of some kind of aether. In other words a magnetic force will appear *if* the particles are moving wrt to an aether. Harry
