Final answer:
Both Technician A and B are correct. Moving a magnetic field across a conductor or moving a conductor across a magnetic field both result in the induction of voltage in the conductor.
Step-by-step explanation:
Both Technician A and B are correct. Moving a magnetic field across a conductor or moving a conductor across a magnetic field both result in the induction of voltage in the conductor. This phenomenon is known as electromagnetic induction. When the magnetic field lines cut across the conductor, it creates a force that pushes the free electrons in the conductor, generating an electric current. This principle is the basis for the operations of various devices like generators and transformers.
