10 Questions
What is the Hall effect?
The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
Who discovered the Hall effect and in what year?
The Hall effect was discovered by Edwin Hall in 1879.
How is the Hall coefficient defined?
The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field.
What did James Clerk Maxwell's paper 'On Physical Lines of Force' contribute to the modern theory of electromagnetism?
Maxwell's paper established a solid mathematical basis for electromagnetic theory.
Where was Edwin Hall working when he discovered the Hall effect?
Edwin Hall was working on his doctoral degree at Johns Hopkins University in Baltimore, Maryland when he discovered the Hall effect.
In what year was the Hall effect discovered and by whom?
The Hall effect was discovered by Edwin Hall in 1879.
What is the Hall coefficient and how is it defined?
The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field.
Who systematized the modern theory of electromagnetism and in which paper was it published?
The modern theory of electromagnetism was systematized by James Clerk Maxwell in the paper 'On Physical Lines of Force', published between 1861 and 1862.
Where was Edwin Hall working when he discovered the Hall effect?
Edwin Hall was working on his doctoral degree at Johns Hopkins University in Baltimore, Maryland when he discovered the Hall effect.
What was one of the questions being explored at the time of the Hall effect discovery?
One of the questions being explored was about the details of the interaction between magnets and electric current, including whether magnetic fields interacted with the conductors or the electric current itself.
