Terms and Conditions
While the special alloys in our magnetic shielding substrates exhibit high magnetic permeability, there are many factors which affect the amount of magnetic shielding you will achieve by using these materials. The list of such factors includes: size and shape of the source of the magnetic field, size and shape of the shielded area, seams in the shielding material, frequency of the magnetic field, distance from shield to source, orientation of shield to the source, thickness and heat treatment of shielding material, etc.
Because we have no control over many of these factors, we cannot and do not guarantee any specific shielding performance for a specific application of these materials. Also, note that foils, ribbons and plates, once cut by us to your specifications, are not refundable.
Here are some basic guidelines for shield design on a circuit box to get you started:
- 1] Naturally, you must first make measurements of the magnetic fields, which are present. Remember to make measurements under various conditions, as the readings will change according to how much electric current is flowing at the time of the reading. Also, find out if there are other sources, such as wiring leading to the circuit box, nearby fluorescent lights, etc.
- 2] Determine how much attenuation (reduction) you want. This will influence the choice for thickness of the Mag-Stop Plate shield, or the number of layers used. Most would recommend that you achieve readings of 2.5 mG or less in areas where people will be spending a lot of time.
- 3] In general, you will extend the shield at least 2 feet beyond the size of the circuit box (or other fairly concentrated source), in all directions. The distance from the shield to the box will be a factor.
- 4] Remember that you will end up concentrating the field at the edges of the shield. In other words, the field will be stronger at the edge of the shield as compared to having no shield at all. So think about positioning the edges away from where the people are likely to be.
- 5] Also remember that you will achieve the greatest % reduction up close to the center of the shield (where the field is strongest anyway). As you back away from the shield, the % reduction decreases.
- 6] Finally, for large shields, one must take saturation into account. This occurs when the Earth's magnetic field (about 400 mG) interacts with a large shield, reducing its effectiveness, unless special “high saturation” (Magnet Shield) shielding alloys are incorporated into the design.
- In the end, some experimenting is often necessary to ensure proper shield thickness and placement.
