Discussion Overview

The discussion centers on the meaning of the unit EMU (electromagnetic unit) in the context of the sensitivity of SQUID magnetometers. Participants explore the definitions and relationships between EMU and other units of measurement, particularly Tesla and Tesla per root Hz.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks clarification on the meaning of EMU in relation to magnetometer sensitivity, noting that they have encountered various conventions for this unit.
  • Another participant suggests using Google to find information, providing a link to a units chart, but does not address the specific context of magnetometer sensitivity.
  • A later reply expresses frustration that general searches did not yield specific information about EMU's application to magnetometer sensitivity, highlighting the confusion around its various definitions.
  • One participant points to a table that outlines the relationship between EMU and Tesla, suggesting that it provides clarity, but does not elaborate on its relevance to the original question.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific meaning of EMU in the context of SQUID magnetometer sensitivity, and multiple views regarding its definitions and applications remain present.

Contextual Notes

There is an acknowledgment of the ambiguity surrounding the definitions of EMU and its relationship to other units, particularly in the context of measuring magnetometer sensitivity.

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 [itex]\left(\frac{T}{\sqrt{Hz}}\right)[/itex]. 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

cheers
