Magnetic fields, magnetic shielding, 2D/3D modeling, measurementsThe key competence of Systron EMV GmbH is to design, sell and install passive magnetic shieldings and active cancellation systems in order to reduce low-frequency magnetic fields. In addition, Systron EMV GmbH performs 2D/3D magnetic field modeling of electrical power stations and on site measurements.

Systron EMV GmbH offers standardised and custom-made shielding solutions. Magnetic shielding is used either to reduce fields at the electromagnetic source, or to protect EMI sensitive tools like electron microscopes or electron lithography machines from stray fields. Systron LabShield^®, a shielding solution for magnetically sensitive equipment, was designed to protect sensitive tools from unwanted stray fields. 

Depending on the application, different shielding alloys are selected for efficient passive shielding. Typically, a combination of nickel iron (mu-metal) or silicon iron (electrical steel) with aluminum is used to shield alternating magnetic fields, while heat treated mu-metal is applied where DC-fields need to be reduced. Alternatively, or in addition, active compensation systems are installed to further reduce magnetic fields.
