    Hello

    We are developing an electromagnet, using sintered metal as the core. It is
    cup-shaped, with a central pole piece. The problem is that there is a very
    high level of residual magnetism. Can anyone advise me as to how we can
    reduce the residual magnetism (which material to add), without
    significantly affecting the pull-force?

    Material is (or similar to) "Powder metal iron as per F0000-5 containing
    0.43% Phosphorus, material density 6.8-7.2g/cm^3".

    Thanks in advance.
