Dear Researchers.
I have a permanent magnet that need to be inserted inside a ferromagnetic cylinder. the magnet has a cylindrical shape made with ferrite and it should be anisotropic (bought from a commercial supplier).
My intend is to study the effect of the tube on the magnetic field intensity. I tried with a magnetometer MG3002 to measure the induction of this magnet before and after it's insertion on the tube in the same point but the results where inconsistent and I could not get the same results twice.
The FEM model show show after a magneto-static test the the induction decrease after the insertion of the magnet inside the tube. yet I would like to prove that experimentally and have a near FEM results values which I believe it's hard to have.
So I would real appreciate any suggestion or feedback from you about this matter.
Thank you
Perhaps you can try to use Hall sensor which is much smaller,e.g. https://ie.farnell.com/diodes-inc/ah49ez3-g1/hall-effect-sensor-40-to-85deg/dp/3373778
