Magnetic Field Sensor - CI-6520A



PASCO's Magnetic Field Sensor is sensitive enough to detect the earth's magnetic field.
Its application in the physics lab includes measuring and plotting fields in single or Helmholtz coils, solenoids, electromagnets and magnets.


  • Measures radial or axial fields: Two switch-selectable Hall Effect sensors measure either radial or axial fields.
  • Tare button: Zeroing or nulling out existing fields is accomplished by just pushing the Tare button.
  • Measurements from earth's magnetic field to strong magnets.
  • Three switchable ranges of sensitivity: Full scale ranges of 10, 100 and 1,000 gauss.
  • 7.5 cm probe: Sensors are mounted at the end of a fully encapsulated 7.5 cm long probe.

PASPORT or ScienceWorkshop?

PASPORT sensors connect directly to all current PASCO interfaces.

ScienceWorkshop sensors connect directly to the 550 and 850 Universal Interfaces as well as legacy ScienceWorkshop interfaces.  They can connect to other PASCO interfaces with the use of an adapter. More info.
