VLF/ELF MAGNETIC Field Shielding & Mitigation DC~3KHz (1GHz + options)

Global EMC have ‘in depth’ knowledge of magnetic near field shielding materials and techniques. All of our ‘on site’ projects have met performance targets in terms of ‘quiet zone’ specification.

Typical magnetic field shield applications are:

Retro & New Installed Magnetic Field Shielding

Global EMC Installations

Different magnetic field environments demand different magnetic field shielding solutions. Global EMC have historically installed:

So as to understand shield material choices Global EMC have carried out comparative material tests:

coil and probe under calibration

Coil and probe under calibration

aluminium shield under test

tangential field tests

Tangential field tests


pure/soft Iron with radiating coil

The findings are not necessarily in line with industry ‘rumours’ on material specification/performance.
