A piece of metal moving West to East in a North to South fixed magnetic field slows down...but how? Yes of course eddy currents are set up in the metal and these currents generate their own magnetic field which somehow slows down the moving metal piece...but how does this actually slow the moving metal down? I can't imagine a counter magnetic force , generated by the moving metal, that would slow the metal down, as the fixed North/South field is perpendicular to the West/East motion of the metal. And yes I understand that the induced eddy currents in the moving metal will generate heat which is then dissipated (radiated as infra red light), but what West/East force is exerted on the moving metal to slow it down?
