In a new lab experiment, two parallel vertical metal rods are separated by L=1.5 m AR=2.0-2 resistor is connected from the top of one rod to the top of the other. A m = 0.28-kg horizontal metal bar falls between the rods and makes contact at its ends with → the rods. A B field of 0.50 x 10T points horizontally between the rods. The bar should eventually reach a terminal falling velocity (constant speed) when the magnetic force of the magnetic field on the induced current in the bar balances the downward force due to the gravitational pull of the Earth

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
