Emf is induced in the loop only and only if there is change in magnetic flux as per Faraday's law
Now as per the given situation area and magnetic field(zero) both are constant
Therefore there will no induced emf in the loop
Now as I=V/r .V=0 therefore i=0
No current will induce

(10 Points. Show your work/explanation for full credit) As shown in the figure, two parallel wires carry a current I in opposite directions, and this current is decreasing. A rectangular loop is centered between the wires. The direction of the induced current through the resistor R is I'm R b O from b to a. alternating. Therefore, it goes from a to b for a moment and then b to a later from a to b. No...
