Hall Effect | Measurement, Hall Coefficient & Precautions |

In this video, we explain the Hall Effect — the development of a transverse voltage across a conductor or semiconductor when placed in a perpendicular magnetic field. This phenomenon occurs due to the Lorentz force acting on charge carriers, leading to the accumulation of charges on one side and generating a measurable Hall voltage.

We also demonstrate the experimental setup used to measure the Hall voltage and calculate the Hall Coefficient (R_H) using the formula:

𝑅_𝐻 = 𝑉_H t/𝐼 B
​

where
𝑉_𝐻 is the Hall voltage,
𝑡 is sample thickness,
𝐼 is the current, and B is the magnetic field strength. The Hall Coefficient helps determine the type and concentration of charge carriers in a material.

The video also covers essential precautionary measures for accurate results, such as ensuring good ohmic contacts, maintaining a uniform magnetic field, and avoiding temperature fluctuations.
