I don't want SHIELDINGS for electro magnet, want for normal magnets. Is there any dealer near me? Can I have any address of dealers,distributers or magnetic field shielding manufacturer ? Will be appreciated for giving useful answers.

Answer 1

Mu-metal is about the only type of magnetic shielding available, however, you need to find someone who will fabricate it and anneal it for you post fabrication. Buying sheets of it, and then forming them without annealing after the fabrication operation will degrade its performance substantially. I did a quick search on google for mu-metal and New Delhi, and a number of firms show up.
