Goal

Provide a lightweight, inexpensive, non-ferrous magnetic shield that deflects magnetic fields away from protected equipment, reducing magnetic interference.

Problem

Magnetic interference from power lines and electronic equipment causing image distortion, data errors, operator fatigue, and the drawbacks of traditional heavy, ferrous shielding materials (steel, mu-metal, etc.).

Concept Summary

A powdered composite shielding material composed of coal slag, silver powder, a calcium-magnesium-zinc powder mixture, and silica powder (optionally nano-silver). The powder can be applied to any substrate as a coating or spray-able layer. The non-ferrous, non-magnetic composition is intended to deflect magnetic fields rather than trap them, avoiding saturation and reducing weight and cost.

Principles

  • Magnetic field deflection
  • Non-ferrous composite shielding
  • Powder-based coating application
  • Use of nano-silver for enhanced conductivity and reflectivity

  • Nano-silver

Mechanisms of Action

  • Deflection of magnetic field lines by non-magnetic composite layer
  • Reflection of electromagnetic energy via silver particles
  • Insulation provided by silica and coal slag matrix

Applications

  • Electronic equipment shielding
  • Medical device shielding
  • Industrial machinery protection
  • Power line interference mitigation

Claimed Performance

The shield deflects magnetic fields of high-power magnets and prevents magnetic saturation of the shielding material.

Limitations

  • No quantitative performance data provided
  • Exact chemical reactions during mixing are not understood
  • Long-term durability and environmental stability not demonstrated

Red Flags

  • Inventors admit they do not understand the exact reactions occurring when the chemicals are mixed
  • Claims are made without supporting experimental data
