Magnetic Testing for Permanent Magnet Supplier Evaluation in Automotive Industry How a US-based automotive and engineering company used magnetic testing to build real confidence in Indian permanent-magnet suppliers. A leading US-based automotive and engineering company, with operations in Pune, wanted to understand magnetictesting before treating it as a decision-making tool — and before choosing its Indian magnet suppliers. Rather thanjumping straight into testing, they first wanted to understand...

Magnetic Powder Testing: From Raw Powder to Full Results Discover how structured magnetic powder testing helped generate complete magnetic properties by combining Fluxmeter and DC Electromagnet testing with proper sample preparation. The material received for testing was in powder form, and the objective was to determine key magnetic properties including Remanence (Br), Saturation, Coercivity (Hc), and Maximum Energy Product (BHmax). However, due to the absence of a defined...

Magnetic Testing of Pressed Powder Sheets Material Background: A manufacturing client approached us with a pressed powder sheet material that required detailed magnetic testing before it could be finalized for application use. The material had been produced through a compaction process and was structurally different from conventional laminated electrical steel. Because of its powder-based composition, the client wanted a clear understanding of how it would behave magnetically—particularly in...

Measured with Precision-Trusted with Confidence Some projects are remembered not only for the data they generate, but also for the confidence theybuild. This case is about a leading drive systems manufacturer that required accurate stack testing ofstator assemblies to ensure product reliability. The Challenge Accurate stack testing was required for stator assemblies. Result needed to meet international benchmarks. Even small magnetic loss variation could affect reliability. Precision was...

Turning a Testing Challenge into a Stronger, More Reliable Process A customer required magnetic testing of curved ferrite segment magnet samples to validate compliance withdefined specifications. Results were to be benchmarked against international laboratory data, making measurementaccuracy and repeatability critical. Standard magnetic testing protocols require strict surface flatness and minimumthickness control to ensure uniform magnetic field distribution — but the supplied samples were curved ingeometry. Root Cause Analysis...
