Question

Discuss how the Hall effect could be used to obtain information on free charge density in a conductor​

Answer 1

Answer:

The Hall effect can be used to measure fluid flow in any fluid having free charges, such as blood. The Hall emf ε is measured across the tube perpendicular to the applied magnetic field and is proportional to the average velocity v.
