Voltage is generated in a conductor when which condition occurs?

Voltage is generated when the magnetic flux through the conductor’s circuit changes with time. This happens when a magnetic field moves relative to the conductor, or the conductor moves through a magnetic field. In the scenario described, the magnetic field moving through the conductor changes how much magnetic field links with the circuit, producing an EMF. The other situations don’t induce voltage because they don’t create a changing magnetic flux: heating doesn’t affect magnetic flux, a stationary conductor in a static field has constant flux, and simply rotating in air won’t guarantee a changing flux unless a magnetic field and closed loop are involved.
