Why would you need magnetic shielding ?
Magnetic shielding is a cost effective solution that reduces magnetic fields to acceptable levels for commercial and scientific applications. These are the 3 major types of shielding systems employed to attenuate electromagnetic fields:
AC ELF Magnetic shielding
Magnetic shielding reduces electromagnetic fields from primary and secondary feeders, risers, transformers, electric panels, switchgear rooms, overhead and underground transmission lines.
DC Magnetic shielding
DC Magnetic shielding reduces magnetic fields from large ferromagnetic moving masses and the natural geomagnetic field of the earth.
Radio Frequency shielding
Radio Frequency shielded enclosures reduce radio frequency interference (RFI) from electromagnetic interference.
