A vertical wire carries a current vertically upward in a region where the magnetic field vector points toward the north. What is
the direction of the magnetic force on this current due to the field? A) downward B) toward the north C) toward the east D) toward the south E) toward the west Two long parallel wires placed side-by-side on a horizontal table carry identical size currents in opposite directions. The wire on your right carries current toward you, and the wire on your left carries current away from you. From your point of view, the magnetic field at the point exactly midway between the two wires A) is zero. B) points upward. C) points downward. D) points away from you. E) points toward you.
