Kerr - June 2, 2016

                   We discussed a few key ideas today:

• Photo-Elastic Modulator or Acoustic Opto-Manipulator (eg; Bathroom scale)

• A Metal's Saturation levels when it comes to Magnetic fields polarizing/aligning their electrons

• Iron Saturates at around 2.2 Tesla (22000 Gauss)

• The Magnets Riad wants to use have a strength of around 1500-2000 Gauss (.15-.22 Tesla)

• We need to look into Metals that saturate at a lower level near the magnetic field that Riad will be using.

This link has a few metals we might consider on Page 214 of the PDF, table 9.2
