MuRoom® Magnetically Shielded Rooms (MSRs)
for Low-Frequency Magnetic Field Attenuation
Engineered for precision research
MuRoom® is a high-performance, modular or custom-built magnetically shielded room (MSR) engineered to reduce extremely low-frequency (ELF) magnetic fields.
Designed for sensitive environments in neuroscience, quantum computing, electron microscopy, and advanced research, MuRoom® delivers exceptional shielding performance with optional degaussing and active magnetic field cancellation.
Product Overview
The MuRoom® is a freestanding magnetic shielding enclosure constructed with MuMetal®, a high-permeability nickel alloy ideal for shielding low-frequency magnetic fields. Each unit is tailored for customer-specific requirements, including:
Internal working volume
Shielding factor and frequency range
Custom doors, cable entry, and equipment integration
Optional RF shielding
MuRoom® systems are optimized for research hospitals, labs, R&D centers, and universities.

Electronics Integration & Custom Systems
Magnetic Shields USA offers a full suite of custom-built electronics for use with shielding systems:
Low-noise current drivers (customizable current ranges and output channels)
Degaussing controllers and software
Active field cancellation modules
Custom test rigs and control interfaces
Electronics are designed, built, and tested in-house for maximum quality control and performance assurance
Degaussing: Precision Demagnetization
To achieve ultra-low residual magnetic fields below 2nT, MuRoom® can be equipped with a precision degaussing system. This eliminates the residual magnetism (~30nT) typically found in MuMetal®.
Features
- Field gradients below 1nT/m
- Output optimized for performance and application type
- Software-controlled “one-button” operation
- Compatible with custom MuRooms and standalone shields
Typical Degaussing Use Cases
- Functional brain imaging (MEG)
- Quantum device calibration
- Magnetometer development
- Magnetic field metrology and testing
Active Magnetic Field Cancellation
Our patented active shielding system dynamically cancels ambient magnetic fields inside the shielded room, delivering industry-leading performance.
System Highlights
- Shielding factor > 50,000
- Real-time residual field control (<1nT)
- Flat-panel or cylindrical coil geometries
- Optional flexible PCB-printed coils for curved or wearable applications
- Optimized for large volumes up to 1 cubic meter (35.3 ft³)
Applications
- Wearable MEG systems
- Quantum computing environments
- Gravity sensors
- Optically Pumped Magnetometers (OPMs)
- Magnetic field mapping and calibration systems
