It seems like your question is related to electromagnetic induction, emf, and the direction of induced current in a specific scenario. However, you haven't provided the details of the scenario or the values involved, such as the rate of change of magnetic flux or the orientation of the circuit.
To determine whether the emf causes an induced current in the direction CDEF or CFED, I would need more information about the setup and the relevant values. If you can provide those details, I'd be happy to assist you further.
