    Sensitivity Unit
AI Thread Summary
The discussion centers on the use of EMU (electromagnetic unit) in the context of SQUID magnetometer sensitivity. Participants highlight the confusion surrounding EMU due to its various conventions and seek clarity on its specific application for magnetometer sensitivity. It is noted that magnetometer sensitivity is typically expressed in Tesla or Tesla per root Hz, making the relationship to EMU unclear. Some resources are shared to clarify the definitions and relationships between these units. Ultimately, the conversation emphasizes the need for precise understanding of EMU in relation to magnetometer performance.

hi there

Google is a wonderful thing :wink:

make sure you read the footnotes :smile:

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

cheers
