You are standing directly under a high-voltage power line thatis 4.5m above you, and a detailed map that you have indicates thatthe power line runs exactly north to south. Your compass needlemakes an angle of 32 degrees to the east with respect to the powerline's direction. a)Knowing that the magnitude of the Earth'smagnetic field is approximately 5.0*10^-5 T, determine themagnitude and direction of the magnetic field produced by the powerline at ground level. b)How much current is being carried by thepower line? c)Is the current flowing toward the north or toward thesouth?
