Theory & Design
Designing and fabricating high-performance magnetic shields begins with understanding the mechanics behind shielding theory.
Even though they cannot be seen or measured directly, magnetic fields exist everywhere. They are invisible fields created anywhere that there is an (AC) electric current such as power cords, power lines, transformers, motors, superconducting magnets, and power supplies. Magnetic fields are also created by (DC) power sources, permanent magnets, and the earth's molten iron core.
Magnetic fields cause a compass to point north and allow us to communicate with people around the world. In certain cases, however, these fields interfere with the operation and accuracy of electronic components and equipment. Magnetic shielding ensures that these sensitive pieces of equipment operate properly.
While the strategies are different, we are able to shield both AC and DC magnetic interference using specially processed magnetic shielding materials. These materials can be designed and fabricated into the optimum magnetic shield with the application of some basic magnetic principles and an understanding of the environment in which the shields will be used.
We bring nearly 45 years of practical experience to the design and engineering of the optimum magnetic shield for each unique application. While we routinely employ our 3-dimensional engineering and modeling capabilities, our technical staff enjoys working with our Clients to collaborate on designing the most cost-effective shielding solution for each application.
