What Laboratorio Elettrofisico does

Laboratorio Elettrofisico (LE Group), founded in 1959 and headquartered in Nerviano (Milan), Italy, is a privately-held engineering firm that designs, manufactures, and services industrial magnetizing equipment and magnetic measurement instruments. The company operates as Laboratorio Elettrofisico Engineering srl a socio unico (sole-shareholder structure) with wholly-owned subsidiaries/offices in Lake Orion, Michigan (USA); Shanghai (China); and Hanoi (Vietnam), and has served over 2,000 clients worldwide across automotive, e-mobility, consumer electronics, medical, aerospace, and renewable energy verticals.

Its product portfolio spans three integrated layers. First, the i Mag™ series of capacitor-discharge magnetizers (Micromag, MicroCal, Master, Master PLUS) covering energies from low (sub-3 kJ benchtop) to very high (up to 120 kJ industrial) applications. Second, a custom magnetizing fixture family — Bitter and wound solenoids, radial and axial multipolar fixtures, sensor fixtures, and magnetic calibration systems — engineered per application via FEA-based electromagnetic, thermal, stress, vibration, and tolerance analyses. Third, a comprehensive magnetic measurement line: AMH-series hysteresisgraphs (including the 2025 AMH-500-P), AMH-series permeameters up to 1 MHz, the AMH-5800 Hard Metal Magnetometer, PFMM permeameter for feebly magnetic materials, digital fluxmeters, single- and 3-axis Helmholtz coils, and high-resolution in-line magnetic scanners (80,000 points/revolution, 5 s cycle). These products are unified through proprietary Xenon and Helium software platforms and consolidated into all-in-one Magnetizing Stations that embed magnetization, handling, cooling, measurement, and QC into production lines using industrial automation components from Siemens, Keyence, Pilz, Festo, Euchner, and Cognex. All instruments comply with relevant IEC 60404 and ASTM standards.

The revenue model is a hybrid of custom-engineered capital equipment sales (the dominant revenue stream, with high unit values for all-in-one stations) plus recurring professional services — calibration of fluxmeters, gaussmeters, Hall probes, Helmholtz coils, and solenoids from certified labs in Italy and Michigan, magnetic measuring services per IEC standards, and FEA-driven custom magnetic design engineering. All pricing is quote-based with no public pricing. Go-to-market is direct enterprise field sales through four regional offices with named Key Account Managers, supplemented by an event-driven motion across major magnetics and e-motor industry trade shows (Coiltech, CWIEME, The Magnetics Show, VIMF, Automotive Meetings Queretaro). The company is certified to ISO 9001:2015 and ISO 14001:2015, is recognized as one of Foxconn Technology Group's top three global suppliers for Apple production (MacBook, iPad, Apple Watch), and has been an Apple Italian Clean Energy Supplier since 2022.
