Study Notes
The Hall Effect
- Edwin Hall discovered the Hall effect in 1879.
- The Hall effect is a phenomenon in which a voltage difference is produced across a conductor when it carries an electric current and is placed in a magnetic field perpendicular to the current.
- The Hall coefficient is a measure of the strength of the Hall effect in a given material.
Hall Coefficient
- The Hall coefficient depends on the type of material, its temperature, and the strength of the magnetic field.
- It is a constant of proportionality that relates the Hall voltage to the product of the current density and the magnetic field strength.
History of Electromagnetism
- The modern theory of electromagnetism was systematized by James Clerk Maxwell in the late 19th century, leading to a fundamental shift in the understanding of electricity and magnetism.
- Maxwell's work built upon the discoveries of earlier scientists, including Michael Faraday and Andre-Marie Ampere.
