Question

Consider a classical Hall bar, no quantum effects. If a magnetic field is applied the standard undergraduate treatment tells us that the Lorentz Force will lead to a build up of excess charge on one side of bar. This charge imbalance leads to a voltage between the two opposing sides, perpendicular to the current passing through the Hall bar. Now consider a superconducting bar deposited prepedincularly to the hall bar under consideration. If the magnetic field is smaller than the critical field, how does this superconducting strip influence the hall voltage/resistance?

Answer 1

The superconducting strip does not influence the Hall voltage or resistance.

Step-by-step explanation:

The Hall effect is a phenomenon where a magnetic field applied to a conductor causes a voltage to develop across the conductor, perpendicular to the current flowing through it. This voltage is known as the Hall voltage. If a superconducting bar is placed perpendicular to the Hall bar and the magnetic field is smaller than the critical field, the superconducting strip will not influence the Hall voltage or resistance.
