Given its generating current, this quantity can be calculated by the Biot-Savart law or Ampere's law.
In the Paschen-Back effect, this entity causes a disruption in the coupling between the orbital and spin angular momentum. If this entity is perpendicular to a current in an electrical conductor, it causes a potential difference in the Hall Effect. Its contour integral is related to the surface integral of total current density in an equation later modified to include displacement current. It causes splitting of spectral lines in the Zeeman effect. Given its generating current, this quantity can be calculated by the Biot-Savart law or Ampere's law. For 10 points, name this type of field caused by a moving electric charge that is measured in Tesla and symbolized B.
