Magnetic Shielding

Magnetic Shielding Solutions for Sensitive Electronics and Precision Applications

Eagle Magnetic has specialized in meeting the challenges and shielding needs of the medical, scientific, government, aerospace, and research community for over 50 years. We design and manufacture custom magnetic shielding solutions, prototypes, and production assemblies using high-permeability alloys, including MuMetal, nickel-iron, and carbon steel.

From prototypes to full-scale production shielding assemblies, Eagle has helped design and produce components for use in:

  • Nuclear medicine and imaging systems
  • Atomic accelerators and radiation control
  • Aerospace and jet fighter electronics
  • U.S. Department of Defense projects
  • Instrumentation, sensors, and laboratory equipment
  • Commercial electronic devices requiring EMI/EMC protection

Our team supports shielding design from concept through manufacturing. Using CAD modeling, CNC machining, forming, and magnetic annealing, we ensure shielding components meet performance, tolerance, and permeability requirements.

Why Magnetic Shielding Matters

Magnetic shielding protects sensitive equipment from low-frequency magnetic fields and electromagnetic interference (EMI). Shielding prevents distortion, data loss, inaccurate readings, or complete component failure in sensitive electronic systems. Eagle Magnetic manufactures shielding solutions designed for performance, dimensional accuracy, and material integrity.

Materials We Work With

We manufacture magnetic shielding using:

  • MuMetal (80% nickel-iron)
  • Nickel alloys and Permalloy
  • Silicon steel and carbon steel
  • Cobalt and specialty ferromagnetic materials

Our Magnetic Shielding Capabilities

  • CAD-assisted shield design
  • CNC machining and sheet metal forming
  • Magnetic annealing for improved permeability
  • Assembly, finishing, powder coating

Whether it’s a simple shield for a commercial device or a precision-made component for aerospace or defense equipment, we build each part to meet the required dimensions and material performance.

FAQs

1. What does a magnetic shield protect against?
A magnetic shield blocks unwanted magnetic fields from reaching sensitive components. It reduces interference that could affect sensors, imaging equipment, electronics, and precision measurement devices by redirecting or absorbing magnetic fields.
2. Which materials are commonly used for magnetic shielding?
Common shielding materials include MuMetal, nickel-iron alloys, Permalloy, silicon steel, and carbon steel. Each material provides different permeability and performance depending on the application.
3. Can magnetic shielding be custom-designed for my application?
Yes. Magnetic shields can be custom-designed based on geometry, material type, operating frequency range, and required attenuation. Most custom shields are engineered with CAD software and manufactured through forming, CNC machining, or metal fabrication.
4. Does annealing improve the performance of magnetic shielding materials?
Yes. Magnetic annealing enhances permeability and relieves internal stresses within materials like MuMetal, making them perform more effectively by guiding magnetic fields away from protected areas.
5. Which industries rely on magnetic shielding?
Industries that depend on magnetic shielding include aerospace, medical imaging, defense, scientific research, electronics manufacturing, instrumentation, and sensor protection sectors.
6. Is powder coating compatible with magnetic shielding materials?
Yes. Powder coating can be applied to steel and nickel-alloy shields to improve durability and corrosion resistance, as long as the process does not negatively affect magnetic performance.
7. How do I know which shielding material is best for my project?
The ideal material depends on the required attenuation, operating frequency, weight limits, cost targets, and environmental demands. Engineers typically compare MuMetal, steel, and nickel-iron alloys to select the best shielding solution.
