Hall Effect vs. Quantum Hall Effect: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 13, 2023
The Hall effect is the generation of voltage across an electrical conductor in a magnetic field, while the Quantum Hall effect is a quantum version observed at very low temperatures and strong magnetic fields, showing quantized Hall conductance.

Key Differences

The Hall effect occurs when a magnetic field is applied perpendicular to the flow of electric current in a conductor, creating a voltage across the conductor. The Quantum Hall effect, however, is observed in two-dimensional electron systems at very low temperatures and under strong magnetic fields, demonstrating quantized Hall conductance.
