Electromagnetic pollution is a fact of our modern lives, with implications for our health, safety and security. The widespread use of electronic systems and their increasing sensitivity make the issue of electromagnetic compatibility (EMC) more and more important.

Examples range from computer screens that wobble if too close to a source of electricity, to medical sensors that are so sensitive that they have to be protected from the earth's magnetic field. If the source of electromagnetic interference cannot be removed, the solution is shielding.

The high permeability of Imphy's magnetic alloys make them ideal materials for shielding against low frequency electromagnetic interference (EMI).
