Main uses of magnetically shielded drums

The main uses of magnetic shielding drums (sometimes called magnetic shielding cylinders or magnetic shielding rooms) are wide-ranging and mainly involve the following aspects:
First, reduce or eliminate magnetic field interference
Electronic equipment protection: In electronic equipment, current flow not only generates magnetic fields, but also may cause radiation of signals, thus affecting the normal operation of the equipment. Magnetic shielding barrel through its high magnetic permeability materials (such as PoMo alloy) shielding effect, effectively reduce or eliminate the interference of external magnetic field on the internal circuitry of the equipment, to ensure that the equipment can operate stably.
High-precision Measurement: In applications requiring high-precision magnetic field measurement, such as magnetocardiography and magnetoencephalography in biomedical research and magnetic field detection in geological exploration, the magnetic shielding barrel can provide a low-field environment to reduce the interference of the external magnetic field, thus improving the accuracy and reliability of the measurement.
Second, scientific research and experiment
Physics experiments: In physics research, magnetic shielding barrels are often used in various experiments involving magnetic fields, such as magnetism experiments, quantum mechanics experiments and so on. It can provide a stable and low magnetic field environment for experiments to ensure the accuracy and reproducibility of experimental results.
Biomedical research: In the field of biomedicine, magnetic shielding barrels are used to provide a zero magnetic environment for high-precision magnetic measuring equipment such as SERF (Spin-Exchange Relaxation-Free) atomic magnetometers, in order to carry out measurements and researches on weak magnetic fields such as cardiac magnetism and cerebral magnetism.
Industrial Applications
Non-destructive testing: In industrial production, magnetic shielding barrels can be used for non-destructive testing of materials and equipment. By detecting the distribution and change of magnetic field inside the material, potential defects and hidden dangers can be found to improve product quality and production safety.
Electromagnetic compatibility testing: In electromagnetic compatibility (EMC) testing, magnetic shielding barrels are used to simulate a low magnetic field environment to test the performance and stability of electronic equipment under specific magnetic field conditions.
Other Applications
Environmental protection: In the field of environmental protection, magnetic shielding barrels can be used to monitor the magnetic field changes in the environment, to understand the pattern of change of the earth's magnetic field and the factors affecting it, and to provide strong support for environmental protection and disaster warning.
Military use: in the military field, magnetic shielding barrels can be used in anti-submarine warfare and other underwater operations, through the detection of submarines and other underwater targets generated by the magnetic field anomalies to achieve the detection and identification of the target.
