Can someone explain in detail if halls effect is magnetic induction?
The answer is no. For details, read this first, then come back if you still have questions. https://en.wikipedia.org/wiki/Hall_effect
An induced emf is generally considered to be due to a changing magnetic flux linkage (Faradays laws)
The Hall emf is caused by a magnetic field (not necessarily changing) causing charge carriers (electrons in a metal) being deflected by the magnetic field.
