Static Magnetic Field Immunity Test Method – Assessing the Effect on Electronic Devices

The static magnetic field immunity test is essential for evaluating how electronic devices and components of various kinds react when exposed to static magnetic fields. These tests are particularly important for a wide range of products, including automotive components, data storage devices such as hard drives and SSDs, electronic payment devices, industrial equipment, security and surveillance devices, renewable energy systems, electric vehicles and their components, batteries, electric motors, wind turbines, alarm and video surveillance systems, PLCs, military devices, SIM and SD cards, POS terminals, pacemakers, defibrillators, credit cards, smartphones, sensors, actuators, electronic and electrical components like sensors, actuators, and many others.

These tests are crucial to ensure that devices operate correctly and safely even when exposed to intense magnetic fields, which can vary greatly depending on the usage environment. This is a fundamental consideration not only for the product's safety and reliability but also for compliance with international electromagnetic safety standards.

The testing method involves exposing the device or component to a controlled intensity static magnetic field. The evaluation focuses on functional behavior, data integrity, and the presence of operational anomalies or physical damage. The procedure and test specifications may vary depending on the type of product and applicable standards, ensuring a comprehensive and reliable performance assessment under exposure to magnetic fields.

The resulting documentation provides crucial information on devices' resistance to static magnetic fields, aiding manufacturers in designing more resilient and compliant products, and informing users about the safety and reliability of the devices in various operational environments.
