Conversion of emu measurement to Tesla

Click For Summary
SUMMARY

The discussion focuses on converting magnetic measurements from emu to Tesla, specifically in the context of data obtained from a Vibrating Sample Magnetometer (VSM). The user questions whether VSM measurements are reported in emu/cm³ and seeks clarification on the conversion process. The conversion involves using a factor of 1000 to convert emu/cm³ to A/m, followed by a factor of 4π x 10^-7 to convert A/m to Tesla. The user encounters issues with unit cancellation during the conversion process.

PREREQUISITES
  • Understanding of magnetic measurement units (emu, A/m, Tesla)
  • Familiarity with Vibrating Sample Magnetometer (VSM) operation
  • Knowledge of unit conversion techniques in physics
  • Basic grasp of magnetic properties of materials
NEXT STEPS
  • Research the specifics of VSM measurement reporting standards
  • Learn about the conversion factors between emu, A/m, and Tesla
  • Study the implications of volume in magnetic measurements
  • Explore additional resources on magnetic properties and their conversions
USEFUL FOR

Researchers, physicists, and materials scientists involved in magnetic measurements and conversions, particularly those working with VSM data and seeking to standardize their results in Tesla.

Homework Statement



I took a Moment vs field measurement of magnetic thin film taken on a VSM. The Bs of the material is given in emus. I want to convert this to a moment value in Tesla as it is typically given in publications.

Are VSM measurements actually emu/cm3 despite being given as emu? If so, I may have some progress toward the solution.


Homework Equations


emu/cm3 to A/m with a converstion factor of 1000
A/m to Tesla with a converstion factor of 4*pi*10^-7
Dividing this answer by the volume I think should give a Bs value in Tesla.

However, my units do not cancel correctly to tesla with this method.

Has anyone had experience with this conversion? Thanks!
