10 Questions
Who discovered the Hall effect?
Edwin Hall
What is the Hall effect?
Production of a potential difference across an electrical conductor transverse to an electric current and an applied magnetic field
What does the Hall coefficient represent?
Ratio of induced electric field to the product of current density and applied magnetic field
What does the Hall coefficient depend on?
Type, number, and properties of the charge carriers in the current
When was the modern theory of electromagnetism systematized?
1861-1862
How did Meißner and Ochsenfeld discover the Meissner effect?
By measuring the magnetic field distribution outside superconducting tin and lead samples
What is the Meissner effect?
The expulsion of a magnetic field from a superconductor during its transition to the superconducting state
What happens to the interior magnetic fields of superconducting samples during the Meissner effect?
They are cancelled nearly all
What does the Meissner effect demonstrate about superconductors?
They are more than just perfect conductors
When does the Meissner state break down?
When the applied magnetic field is too strong
