Suppose that you place a loop with its face perpendicular to a uniform magnetic field. If the magnetic field points directly at you as you look at the loop, in what direction does the induced current flow around the loop if
-(a) the magnetic field is static.
A) The induced current flows clockwise.
B) The induced current flows counterclockwise.
C) No current flows in the loop.
D) A current flows, but one needs additional information to determine the direction in which it flows.
E) One needs additional information to determine even whether a current flows or not.

No current is induced in the loop by a static magnetic field according to Faraday's law of electromagnetic induction, which states that a changing magnetic field is necessary to induce an electromotive force (and thus current) in a loop.
