New Hall Effect Discovery Challenges Long-Standing Physics Rule
A team at Carnegie Mellon University has observed an unexpected variant of the Hall effect that contradicts the century-old assumption that this electrical response requires a perpendicular magnetic field. The finding could lead to revisions in fundamental physics textbooks.

EXPANDED:
The discovery at Carnegie Mellon University challenges a foundational principle in electromagnetism. For over a hundred years, the Hall effect has been understood to require a perpendicular magnetic field to deflect charge carriers. This new observation reveals a variant that operates without that specific field condition.
Because the assumption has
