The diagram represents a wire that is not part of a complete circuit, just above the poles of two magnets. Moving the wire downward between the poles in the direction shown in the diagram will

• induce an alternating magnetic field between the poles of the magnets

• induce a potential difference between the ends of the wire

• decrease the wire’s resistivity

• reverse the direction of the magnetic fi eld
