SUMMARY

The discussion centers on the use of EMU (Electromagnetic Unit) as a unit of measurement for the sensitivity of SQUID (Superconducting Quantum Interference Device) magnetometers. Participants highlight the ambiguity of EMU due to its various conventions and emphasize the standard measurements for magnetometer sensitivity, which are typically in Tesla or Tesla per square root Hertz (T/√Hz). Resources such as the units chart and a table detailing the relationship between EMU and Tesla are provided to clarify these concepts.

PREREQUISITES
  • Understanding of SQUID magnetometers and their applications
  • Familiarity with electromagnetic units, specifically EMU
  • Knowledge of sensitivity measurements in physics, particularly in magnetometry
  • Basic grasp of Tesla and its significance in measuring magnetic fields
NEXT STEPS
  • Research the relationship between EMU and Tesla in detail
  • Explore the principles of SQUID magnetometers and their sensitivity metrics
  • Learn about the measurement of magnetic field sensitivity in T/√Hz
  • Investigate various conventions of EMU and their applications in scientific literature
USEFUL FOR

Researchers, physicists, and engineers involved in magnetometry, particularly those working with SQUID technology and seeking to understand sensitivity measurements in electromagnetic units.

hi there

Google is a wonderful thing :wink:

Thank you for your response, though I would like to tell you that definitely googling it is the first thing I have done, but it doesn't help, because apparently EMU has many different conventions and I'm looking for something specific used for magnetometer sensitivity.

Magnetometer sensitivity is either measured in Tesla or in Tesla per root Hz \left(\frac{T}{\sqrt{Hz}}\right). I cannot relate EMU to that at all.

Best regards.
 
well its definitions are given pretty clearly in this table with its relationship to Tesla
if that doesn't help, then I cannot help you further
