Direction of current in a wire connecting two conducting loops placed concentrically in a time varying magnetic field which is into the plane of paper
Think about a regular AC mains transformer with two isolated secondary windings. You can interconnect the secondaries like this: -



To obtain the same voltage but twice the amps or, you can connect them like this: -



To get twice the voltage and the same amps.

There is no inherent current flow from one winding to the other whether the secondaries are shorted or open circuit - they are isolated.
