Detailed Solution

The above statement is false.
As long as the current constantly flows in coil A, the galvanometer connected with coil B shows no deflection. When no current flows in coil A, the galvanometer connected to coil B will show zero or no deflection. When the current flows through coil A, the galvanometer pointer jumps to one side and returns to zero, indicating a momentary current in coil B.
The correct statement would be that two coils are connected, and if the current flows steadily through coil A, then the galvanometer connected to coil B will show no deflection.
