What happens to the voltage induced in a conductor when the loop is at 180°?

When a conductor is oriented at 180°, it is effectively in a position where the magnetic field lines are perpendicular to the plane of the loop, resulting in no motion through the magnetic field lines. According to Faraday’s Law of Electromagnetic Induction, the induced voltage in a conductor is dependent on the rate of change of magnetic flux through the loop. At 180°, the loop does not cut through any magnetic field lines, meaning that the change in magnetic flux is zero and thus, no voltage is induced.

This is the reason why no voltage is generated at this orientation of the conductor. It contrasts with other positions such as 0° or 90°, where the conductor would either maximize induced voltage or have some measurable effect due to its interaction with the magnetic field.
