5 Questions
What is the Hall effect?
The production of a potential difference across an electrical conductor transverse to an electric current and a perpendicular magnetic field
Who discovered the Hall effect?
Edwin Hall
What is the Hall coefficient defined as?
The ratio of induced electric field to the product of the current density and the applied magnetic field
What contributed to the understanding of the interaction between magnets and electric current?
James Clerk Maxwell's 'On Physical Lines of Force'
On what basis did Edwin Hall reason about the interaction between magnetic fields and conductors?
The force specifically acts on the electric current, crowding current to one side of the wire
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.
