What is the voltage across a conductor that is completely aligned with flux lines?

When a conductor is completely aligned with magnetic flux lines, it means that there is no relative motion between the conductor and the magnetic field. According to Faraday's law of electromagnetic induction, a voltage is induced in a conductor when it experiences a change in the magnetic flux passing through it. When there is no change in flux, which occurs when the conductor is aligned and stationary with respect to the flux lines, there is no induced electromotive force (EMF) generated.

As a result, the voltage across the conductor is zero because the necessary condition for inducing a voltage (the change in magnetic flux) is not met. In this scenario, with the absence of movement or change, the conductor does not experience any potential difference, leading to a voltage of zero across it.
