    Study Notes

    The Hall Effect

    • The Hall effect is a phenomenon observed in conductors when a current is passed through them in the presence of a magnetic field.
    • It was discovered by Edwin Hall in 1879.

    Hall Coefficient

    • The Hall coefficient is defined as the Hall electric field per unit current density per unit magnetic field strength.

    Interaction between Magnets and Electric Current

    • The understanding of the interaction between magnets and electric current was contributed to by the Hall effect discovery.

    Edwin Hall's Reasoning

    • Edwin Hall reasoned about the interaction between magnetic fields and conductors based on the deflection of electric charge carriers in a conductor due to the presence of a magnetic field.
