Advanced Magnet Lab Inc. (AML) now offers Perfect-Field Magnets (PFMs) that deliver stronger magnetic fields and up to 40 times better magnetic-field quality with less power consumption than comparable state-of-the-art Helmholtz coils. The PFMs are also 50% smaller than comparable Helmholtz coils.

Advanced Magnet Lab Inc. (AML) is now offering its first commercially available Perfect-Field Magnets (PFMs) for applications needing highly uniform magnetic fields — including those in quantum computing, manufacturing, research, and medical applications.
The Perfect-Field Magnet works in challenging applications with requirements currently not satisfied by magnets on the market today. PFM offerings are latest product of AML’s R&D driven by proprietary software and past magnet innovations already solving some of the world’s most challenging problems in magnetics. The latter includes magnets for high energy physics particle accelerators, ac losses measurements in superconductors, heavy ion cancer therapy, MRI, and much more.
“It’s really magnetics 3.0; engineers won’t find this with existing solutions that are manufacturable at an economical price,” said Dr. Rainer Meinke, Co-Founder of AML and the inventor of these technologies.
Technological and economical upgrade from Helmholtz Magnets: Dr. Meinke has been busy in the lab developing novel solutions to some of the world’s most complex problems involving magnetics for more than four decades. The Perfect-Field Magnets incorporate a number of these breakthroughs as well as other intellectual property and manufacturing processes … yielding an unmatched product not seen in more than 200 years. More specifically, AML’s Perfect-Field Magnets provide:
- Up to 40x higher magnetic field quality; Greater than 2x increase in magnetic field
- 50% smaller than comparable products — and consuming 40% less power
- Scalable and customizable
PFMs have a field variation in good field region of less than 0.001% with a magnetic field starting at about 50 Gauss … or nearly 100 times earth’s magnetic field.

Today, AML can manufacture magnets with unprecedented magnetic field uniformity in unique geometries — for products that consume less power and space.
Founded in 1995, AML is a magnet supplier dedicated to the development of breakthrough magnet-based products for electric-powered transportation, power generation, medical diagnostics, and treatments and research. For more information, visit www.AML-Enabled.com or www.perfect-field.com.
