Magnetic shielding using a semiconductor?

  1. Oct 5, 2011 #1
    I read an article a week or so ago talking about using a semiconductor to disrupt a magnetic field. Generally a magnetic field can be disrupted by any magnetic material in its path. Steel for a basic example can reduce the realized field on the opposite side from the magnetic field source.

    For my project, a magnetic material is not something I can use to disrupt the magnetic field. I can technically have "some" magnetism to the material, but the lower the better basically. It doesn't have to "block" it 100% or anything, but a higher reduction the better.

    I wish I could find that article and research it a bit more, but for the life of me I cannot locate where I read it. Does anyone have any experience or knowledge on using some approach like a semiconductor for this? Or perhaps some advice? I am in a real pickle with this one and any help or advice would be appreciated more than you know. Thank you in advance.

    *Magnet source is 2 facing n50 neodymium 2x2x1" static magnets. 2" apart and I need the shielding in between these two magnets. To reduce their pull on one another. But also need to mechanically move the shielding out of the way from time to time, hence the magnetism needing to be low in the material.
    *Gauss = 13,800
    *Pull force = 251 lbs
    *No EM source of magnetism of relevant proportion.
