Measuring up to ~2T magnetic fields

Click For Summary
SUMMARY

The discussion focuses on methods for measuring magnetic field flux densities around ~2T, emphasizing safety due to the potential hazards of ferromagnetic materials. Recommended measurement tools include Hall effect probes, integrating (flip) coils, and proton (nuclear magnetic) resonance. For a volume of at least 1 cm³ and a desired precision of 1%, the integrating coil is identified as the simplest solution, requiring only an op-amp circuit and a DC voltmeter for construction.

PREREQUISITES
  • Understanding of magnetic field measurement techniques
  • Familiarity with Hall effect sensors
  • Knowledge of integrating (flip) coils
  • Basic electronics skills, particularly in building op-amp circuits
NEXT STEPS
  • Research the construction and application of integrating (flip) coils for magnetic field measurements
  • Learn about Hall effect probes and their specifications for high magnetic fields
  • Explore proton (nuclear magnetic) resonance techniques for magnetic field measurement
  • Study safety protocols when working with strong magnetic fields
USEFUL FOR

Researchers, physicists, and engineers involved in magnetic field measurement, as well as hobbyists interested in DIY magnetic sensing projects.

What do you propose as a quick DIY method for measuring magnetic field flux densities around ~2T?

I would first and foremost recommend to be very careful with fields at ~2T. A piece of ferromagnetic material can do a lot of damage and get permanently lodged in whatever it is you are using for the field. Is this something like an MRI magnet? What do you need the measurements for?
 
A lot depends on the volume of field avialable (i.e., size of sensor), whether it is an dc or ac field, the precision required, ease of construction, etc.
I have used many types, including Hall effect probes, integrating (flip) coils, proton (nuclear magnetic) resonance. If you have at least 1 cm3 of volume, and you want a 1% precision measurement, an integrating coil is easiest, and does not require anything more than building an op-amp circuit and using a dc voltmeter.
