Hence, the expanding aerospace and defense industry are fueling the growth of the magnetometer market.

Major companies in the magnetometer market are focused on developing innovative products, including AMR (Anisotropic MagnetoResistive) magnetometer sensors, to enhance their profitability. AMR magnetometer sensors measure magnetic fields by detecting changes in resistance due to the orientation of magnetic field lines relative to the sensor's material. For example, in February 2023, MEMSIC Inc., a US-based semiconductor manufacturing company, launched the AMR magnetometer MMC5616WA. These sensors offer advanced features for various applications such as automotive, industrial, and consumer electronics, providing smart and secure sensing of physical motion and displacement. AMR magnetometer sensors are crucial in medical, wearable, and smart home applications for their reliable and intelligent detection capabilities.

In October 2023, Allegro MicroSystems, Inc., a U.S.-based provider of high-performance power and sensing semiconductor solutions for motion control and energy-efficient systems, acquired Crocus Technology for an undisclosed amount. Through this acquisition, Allegro sought to significantly strengthen its magnetic sensor portfolio by incorporating advanced Tunnel Magneto-Resistance (TMR) technology and rapidly expanding its engineering and product development teams, thereby accelerating time-to-market for future sensing solutions. Crocus Technology is a U.S.-based provider of advanced TMR magnetic sensors used across industrial, automotive, and consumer electronics applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on electronic components, magnetic sensing modules, and semiconductor parts have increased production costs for magnetometers, especially affecting fluxgate, optical pumping, and vector magnetometer categories. Regions dependent on imported electronic assemblies, such as Europe and Asia Pacific, face supply chain delays and price fluctuations. However, tariffs have encouraged domestic sourcing, stimulated localized manufacturing of sensor components, and supported innovation toward cost efficient, lightweight magnetometer designs.
