Deep Dive: The Industry Standard for Magnetic Flux Control
Did you know that Fluxtrol’s own Robert Goldstein, FASM, authored the definitive section on Magnetic Flux Controllers for the ASM Handbook Volume 4C?
If you are looking for a rigorous, technical foundation on how these materials influence induction systems, this is the essential reference. The article bridges the gap between fundamental electromagnetic theory (like Faraday’s and Lenz’s Laws) and practical, real-world coil design.
Magnetic Flux Controllers in Induction Heating and Melting
What’s covered in this comprehensive guide:
☑️ The Physics of Reluctance: Understand how flux controllers act as a “magnetic superhighway” to lower the total reluctance of your system.
☑️ Material Selection: A comparison of laminations vs. Soft Magnetic Composites (SMCs) and when to use each.
☑️ Application Case Studies: Detailed looks at ID heating, single-shot hardening, and scan hardening.
☑️ Design Thresholds: Why “more permeability” isn’t always better, and how to find the optimal threshold for your specific frequency.
Whether you are designing a new induction line or optimizing an existing one, the principles outlined in this ASM Handbook section are the roadmap to higher efficiency and better metallurgical results.

Overcoming HF Tube Welding Bottlenecks: SMC Impeder Core Research
Traditional ferrite impeder cores often hit a hard magnetic saturation limit, severely restricting line speeds and wasting energy in HF tube welding systems. At FABTECH 2025 in Chicago, Fluxtrol’s Executive Director of Strategic Planning and Product Development, Rob Goldstein, FASM, presented a game-changing alternative: Soft Magnetic Composite (SMC) impeder cores.
Backed by industrial case studies, offline validation testing, and mill trials, Rob’s research demonstrates how optimizing with SMC materials can deliver 30% to 50% energy savings while unlocking significantly higher production speeds.
You can read the research findings, trial results, and review the complete presentation slides directly on our website. Rob’s full step-by-step breakdown of the research is also available to watch on YouTube.
