You have gathered green turtle hatchlings from a beach where the magnetic field strength is 50 μT and the dip angle is 56∘. You then put the turtles in a 1.1 m diameter circular tank and monitor the direction in which they swim as you vary the magnetic field in the tank. You change the field by passing a current through a 200-turn horizontal coil wrapped around the tank. This creates a field that adds to that of the earth. Part A In what direction should current pass through the coil, to produce a net field in the center of the tank that has a dip angle of 62∘ ? In what direction should current pass through the coil, to produce a net field in the center of the tank that has a dip angle of 62 ? (a)clockwise (b)counterclockwise
