Polymagnets™ – Magnets Designed with a Purpose

CMR collaborated with NASA to develop Polymagnets™ composed of 0.6” thick Samarium Cobalt (SmCo) for a magnetic coupler from 2020 to 2022.  These Polymagnets™ were tested (attachment, shear, and torque forces) and retained force and function at temperatures above 140⁰C and below -180⁰C! 

The article below was published by NASA Armstrong regarding this coupler; the original article is on page 58 at https://www.nasa.gov/sites/default/files/atoms/files/2021-afrc-rte-report.pdf.

Dust-Tolerant Magnetic Coupler for Cryogenic Fluids for Space Applications

This research effort is developing a prototype for a dust-tolerant cryogenic magnetic coupler for lunar applications. The functional prototype demonstrated the integration of three subsystems: a cryogenic fluid coupler, patterned magnets, and dust mitigation. This innovation has the potential to fulfill multiple gaps associated with cryogenic fluid transfer and dust-mitigation technologies. It received a FY2021 Early Career Initiative (ECI) award and will receive $2.5 million over two years to support its work.

Work to date: The team collaborated with NASA’s Kennedy Space Center to develop a cryogenic low force disconnect (LFD) coupler that will enable transference of cryogenic fluid in a lunar representative environment. This coupler has an innovative design that enables the two halves to be connected with minimal force. This research is supporting the continued development of NASA Kennedy’s LFD technology, developed initially under a Center Innovation Fund (CIF) award. The magnetic subsystem involves the use of patterned magnets (Polymagnets™) developed by Correlated Magnetics Research, an external vendor. These Polymagnets™ are tailored to achieve a desired behavior and deliver stronger local force. Conventional magnets generally have far-reaching and weak magnetic fields, whereas printed magnetic poles keep magnetic loops tight and strong. Reduced magnetic field distance also reduces electromagnetic interference (EMI) concerns. The magnetic technology used in this project was also originally studied under an Armstrong CIF award, and this ECI funding has allowed the team to continue to advance the technology.

The erosive and abrasive nature of lunar regolith dust can cause severe damage to equipment and systems. It can degrade coatings used to seal equipment and erode surfaces. The dust mitigation subsystem aims to protect the cryogenic fluid from dust contamination and the coupler’s mechanisms from damage.

Looking ahead: System integration and testing will occur at NASA Armstrong, Kennedy, and Marshall Space Flight Center.


  • Innovative: Combines an LFD coupler that requires less force to mate coupler halves with Polymagnets™ that customize force as needed per project 
  • Protective: Shields cryogenic coupler and fluid from dust contamination


  • Transference of cryogenic fluid in a lunar environment

Thank you, all 1.5+ M of you!

All it took was an enthusiastic engineer, Destin Sandlin, explaining Smart Magnets on a popular website, SmarterEveryday.com. And…nearly 1.5 million YouTube views in days.


At CMR we are grateful today for your interest, enthusiasm and outpouring of ideas on how to use Polymagnets.

Sandlin’s passionate enthusiasm for magnets, engineering, tech and science shine through in the piece where he calls the technology a “game changer” and says, “Polymagnets give new, unique, crazy behaviors [to new products] by manipulating magnetic fields. You’ve never seen anything like it.”

Destin dives into a discussion of patterned magnets, tight versus loose magnetic fields and circuits, to understand how Polymagnets can be “programmed” for unprecedented behaviors such as attraction and repulsion in the same axis. He marvels at how this creates a “spring” where two objects are pulled together until they get very close. Then, they repel so they don’t actually touch, they stop and hover a few millimeters away from one another.

“A new kind of shock absorber,” wrote one commentator.

Then Destin shows his engineering colleagues a pair of Polymagnet Smart Magnets that, when one is rotated (like a doorknob), suddenly lock together. They are beyond intrigued.  “You can create incredible three-dimensional behaviors.” Destin adds.

The video concludes with “The entire foundation of magnetic circuit design technology just changed.”

And you are the ones to create exciting new products.

Design is Make or Break, and Keyssa’s Cool

By Andy Keane, CEO |


Returning from CES, where around 22,000 products were announced, I was reminded again of the immense size and scope of the CE marketplace – and its ferocious competitiveness.  The explosive growth in CE challenges the designer to build a product that will stand out both in features and user experience.

Blah products become commodities in the world of CE faster than a pack of 50 teenagers can condemn them on SnapChat and sentence them to death in the marketplace.

Let’s look at laptops, which so often break at those connectors. Connectors are the bane of electronics, and cause many premature device deaths. You’re at Starbucks working away, when the decaf latte at the next table stands up and snags your power cord, yanking and ruining your connector. Connectors are designed to make trouble, and they do deliver!

Popular Mechanics: This Is Awesome: Printing Your Own Magnets (Video)

The Mini MagPrinter could become the coolest tool to hit maker spaces since 3D printing. It churns out custom magnets using technology that won its creator, Correlated Magnetics Research, a 2010 Popular Mechanics Breakthrough Award. The new Mini is half the size of the original MagPrinter, and it helps product designers prototype their inventions using magnets that have novel behaviors. While most magnets have only one north pole and one south pole, the Mini encodes multiple poles across a magnet’s surface using a focused electromagnetic field. By tailoring the arrangement of the poles and subsequently controlling the magnetic forces, users can create coilless springs, frictionless gears, specialized latches, and even products that self-assemble.

TechCrunch: Alabama-Based CMR Demos Programmable Magnets That Changes Polarity And Strength On A Whim (Video)

Magnets are pretty basic – some poles attract, some repel, and you can use them to hold stuff up on your fridge. However, what happens when magnets can be “programmed” to react in different ways? Huntsville, Ala.-based Correlated Magnetics Research has some magnets that can do some amazing – and slightly spooky – things.

These magnets can “hold together” while still not touching, release from each other with a twist, and even act as a sort of magnetic motor. In one cool demo Stephen Straus, VP of CMR, shows us magnets that repel each other from a certain distance and then, when pushed close enough, snap together. Before you run away screaming “perpetual motion machine,” understand that the laws of physics still apply.
