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:
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
Aluminium shield under test
Tangential field tests
Pure/soft Iron with radiating coil
Probe prior to insertion into shielded cube
The findings are not necessarily in line with industry ‘rumours’ on material specification/performance.
