Summarizing the Hall Effect

Summary

  • The Hall effect is the creation of voltage \(\epsilon \), known as the Hall emf, across a current-carrying conductor by a magnetic field.
  • The Hall emf is given by

    \(\epsilon =\text{Blv}\phantom{\rule{0.25em}{0ex}}(B,\phantom{\rule{0.25em}{0ex}}v,\phantom{\rule{0.25em}{0ex}}\text{and}\phantom{\rule{0.25em}{0ex}}l,\phantom{\rule{0.25em}{0ex}}\text{mutually perpendicular})\)

    for a conductor of width \(l\) through which charges move at a speed \(v\).
