A long straight wire runs up and down vertically and carries current downward. What is the direction of the magnetic field produced by this current at a location nearby and directly east of the wire? A) southward

B) downward

C) upward

D) northward

E) westward

A) southward

Explanation:

Applying the rule of the right hand for the determination of the magnetic field produced by the current flowing through the cable yields the following results: between the wires it is to the north, the west of the wires is to the south and east of the wires, which asks the problem is to the south.
