Watch how essential induction coil types behave when optimized with Fluxtrol’s high-performance soft magnetic composites (SMCs).
In our technical demonstration, we provide a side-by-side look at the physical magnetic field patterns of five common inductor geometries. By comparing these coils with and without Fluxtrol 25, you can clearly see how flux control transforms an inefficient standard process into a fully optimized one, geared toward reducing cycle times and lowering energy consumption.
Equipping your induction coils with SMCs allows you to manipulate the magnetic circuit, forcing flux into the workpiece instead of allowing it to wander into the surrounding air. As shown in the Hairpin Inductor segment, this control can reduce heating cycles by 66%.
Optimizing with Fluxtrol 25 enables your coils to:
- Boost Power Density – Drive more heat into the part without increasing your generator’s power setting.
- Slash Cycle Times – Accelerate heating rates by up to 3x, as seen in our 12s vs. 4s hairpin demonstration.
- Fix Heat Pattern Issues – Manage “end effects” to eliminate soft spots and ensure uniform hardness depth across the entire part.
- Protect Equipment – Prevent accidental stray heating of nearby machine frames, quench rings, and fixtures by keeping the magnetic field where it belongs.
The result is a faster, more repeatable process with tighter metallurgical control. If you are looking to troubleshoot heat patterns or increase throughput on your production line, this visual comparison is an essential reference.

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.
