Two circular loops lie side by side in the same plane. One is connected to a source that supplies an increasing current, the other is a simple closed ring. Is the induced current in the ring is in the same direction as that in the loop connected to the source or opposite? What if the current in the first loop is decreasing?

Explanation

By increasing the current in loop -1, magnetic field in ring -2 in downward direction will increase.
Hence, induced current in ring-2 should produce upward magnetic field. Or current in ring should be in the same direction.
