Saturation:
The magnetic saturation of the shield is given by the magnetic properties of the shield material.
Ferromagnetic material saturates between 0.5 and 2 Tesla. Once the shield is saturated, its apparent Permeability will decline to the value 1, meaning that the shield acts like air. A saturated shield does not guide nor attract magnetic flux lines. Therefore, the shield design has to be chosen such that the field generated by the current and the field generated by external sources do not saturate the shield material.
Magnetic Shielding
With our long experience in electromagnetic engineering and metallurgical knowledge, we are able to offer a complete range of magnetic shielding solutions; from small cans of 12mm diameter or less, up to room size shields which can be supplied in kit form or assembled on site at customer premises.
Magnetic Shields has the facilities to supply all your requirements. From individual multiple layer shields capable of screening down to the very low levels that are typically required in research applications, to high volume production runs of over 50,000 pieces a week for commercial industry.
Our magnetic shields are only produced from the highest quality grades of mu metal to ASTM A753 Alloy 4 and are magnetically annealed in a hydrogen atmosphere to ensure optimum performance and reliability.
