Three identical coils `A,B` and `C` carrying currents are placed co-axially 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
