358671 Two circular, similar, coaxil loops carry equal currents in the same direction. If the loops are brought nearer, what will happen?

1 Current will increase in each loop
2 Current will decrease in each loop
3 Current will remain same in each loop
4 Current will increase in one and decrease in the other

358672 Three identical coils \(A\), \(B\) and \(C\) carrying currents are placed coaxially with their planes parallel to one another. \(A\) and \(C\) carry current as shown in figure \(B\) is kept fixed while \(A\) and \(C\) both are moved towards \(B\) with the same speed. Initially, \(B\) is equally separated from \(A\) and \(C\). The direction of the induced current in the coil \(B\) is
