What you need is some thickness of ferrous metals. https://en.wikipedia.org/wiki/Electromagnetic_shielding#Magnetic_shielding https://en.wikipedia.org/wiki/Electromagnetic_shielding#Magn... https://web.archive.org/web/20070327130322/https://advancemag.com/needfor.htm https://web.archive.org/web/20070327130322/https://advancema... https://interferencetechnology.com/magnetic-shielding-basics/ https://interferencetechnology.com/magnetic-shielding-basics... It's easy to test the efficacy of magnetic shielding yourself if you have a large, powerful magnet and a CRT monitor handy.
