A metal bar of mass m slides frictionlessly on two parallel conducting rails a distance 1 apart A resistor R is connected across the rails and a uniform magnetic field B pointing into the page fills the entire region TE a If the bar moves to the right at speed v what is the current in the resistor In what direction does it flow b What is the magnetic force on the bar R www
