Thank you, all 1.5+ M of you!

By Andy Keane, CEO | March 28

All it took was an enthusiastic engineer, Destin Sandlin, explaining Smart Magnets on a popular website, 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.

  • Is it possible for the polymagnet to switch its magnetic fields from N to S and vice versa for a period of time?

  • is there any place where we can discuss different kind of magnetic design behaviour? i have plenty of ideas!

    • If you find a place, please let me know. I am also super interested in the applications of these magnets. I’d also like to contact somebody from CMR but there “contact us” page is just for orders.

  • Can you design a magnet that pulls at a certain distance, then pushes as you get closer, THEN pulls again as you get even closer, THEN pushes again as you get even closer, etc as many switches as necessary? Like your latches but keep switching more than once?

  • Is it possible to print/program magnets on a radius? Such as a bowl shape, half a sphere.
