Why is low-frequency magnetic shielding different?
Low-frequency magnetic fields can penetrate conductive shields more easily when magnetic permeability is low.
What materials may be needed?
High-permeability alloys or specialized magnetic shielding materials may be required.
What should I provide?
Magnetic-field frequency, source type, field strength, geometry and required attenuation.
Project note: Use supplier data as a starting point. Validate the finished assembly at the relevant frequencies and environmental conditions.
