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 magnetic
testing before treating it as a decision-making tool — and before choosing its Indian magnet suppliers. Rather than
jumping straight into testing, they first wanted to understand our facility and technical capabilities.
The Challenges
Two Conversations, Not One Transaction
- Meeting One
A physical meeting at the Ferrites India facility, where our senior technical team walked through our testing capabilities and what each magnetic parameter actually means.
- Meeting Two
A follow-up meeting focused specifically on sample testing, test methodology, and how the resulting data could support supplier development.

What We Actually Helped With
- Understand different magnetic parameters
- Select the right testing methods
- Interpret magnetic test results, line by line
- Compare magnetic performance across samples
- Recognise why magnetic moment testing mattered
- Build a systematic supplier-evaluation approach
Results:
Combining accurate readings with hands-on report walkthroughs gave the customer real confidence in evaluating
Indian magnet suppliers — confidence that showed up directly in repeat orders for magnetic moment testing.
