Magnetic shielding

The magnetic shielding cylinder is a precision magnetic shield built from multiple layers of high-permeability material (typically permalloy). It attenuates external magnetic interference, including the Earth's magnetic field, to provide a near-zero magnetic environment inside the enclosure.

Features

• Effective attenuation: multi-layer high-permeability design reduces low- and high-frequency magnetic fields.
• Stable performance: engineered for minimal performance degradation in continuous operation.
• Customizable dimensions: range of standard sizes and fully customizable internal/external diameters and lengths.
• Optional configurations: openings, end caps, temperature control and other customer-specific options.

Application areas

• Magnetic sensor R&D, testing and calibration: provides a controlled near-zero magnetic environment for sensor evaluation.
• Magnetometer calibration: ensures measurement accuracy and repeatability.
• Magnetic materials research: experiments on susceptibility, coercivity and hysteresis behavior.
• Weak magnetic field experiments: supports research in magneto-optical effects, low-field resonances and related studies.
• Protection of magnetic-field-sensitive equipment: shields instruments to ensure reliable operation.

Product advantages

• Engineered design: developed by specialists to meet defined shielding specifications.
• Tested performance: validated against performance indicators and quality checks.
• Practical usability: lightweight construction, finished appearance and cost-effective installation and handling.

How to choose a magnetic shielding cylinder

• Required attenuation: select a cylinder specified to provide the necessary magnetic field reduction for your application.
• Internal volume: ensure internal dimensions accommodate the equipment or experimental setup.
• Material selection: choose appropriate high-permeability materials (e.g., permalloy) according to performance needs.
• Additional functions: specify openings, covers, thermal control or feedthroughs when ordering custom variants.

Precautions for use

• Consult the user manual before installation and operation.
• Position the cylinder away from strong external magnetic sources for optimal shielding.
• Avoid mechanical shocks to protect the multilayer shielding structure.
• Perform periodic demagnetization as recommended to maintain peak shielding performance.

Technical specifications

• Typical materials: multi-layer high-permeability materials (e.g., permalloy).
• Internal magnetic flux density: can be reduced to near-zero levels (typical achievable values < 1 nT under controlled conditions).
• Sizes: multiple standard sizes; custom diameters and lengths available on request.
• Optional features: openings, end caps, temperature control and customer-defined interfaces.
• Design attributes: lightweight construction, finished appearance and user-friendly assembly.
