You have the apparatus shown in Figure P21.13. A circular metal plate swings past the north pole of a per- manent magnet. The metal consists of a series of rings of increasing radius. Indicate the direction of the current in one ring (a) as the metal swings down from the left into the magnetic field and (b) as the metal swings up toward the right out of the magnetic field. Use Lenz's law to justify your answers.

Please answer with detailed solution. I have attached the formulas and references that we use. An electric power line carries of 1200 A in a location where the magnetic field of the Earth is 4 x10 ^-5 T. The line makes an angle of 60 degree with respect to the field. Determine the magnetic force on a 100-m length of the wire.
