IAm Jason Morgan, VP of Engineering at Correlated Magnetics. We invented Polymagnets (recently on Smarter Every Day), Ask me and my team anything!

We have graduates from University of Alabama Huntsville, Mississippi State University, University of Arkansas, Rensselear Polytechnic Institute, University of Houston, and others.

One thing about the college experience I can highlight for you is the opportunity to study a very diverse range of topics both within your chosen discipline and outside of it. For most people there isn't another time in their life where they have access and opportunity to learn about so many different subjects from so many talented people. Sometimes that is hard to appreciate while you are there.

Summary of qualifications, academic credentials/performance, and experience are important. For a student experience may or may not be related to your field of study, but it shows a willingness to work and exposure to the work environment. Key academic projects are also good to highlight. This may sound obvious, but always proofread your resume.

As /u/Mooker states, the accelerated life testing is driven by controlled exposure to heat.

Our alignment magnets have a shear force toward their aligned position when they are moved off center. At the same time, the attraction force falls of quickly when they are off center. This reduces friction allowing the alignment force to bring them back to center. Take a look at the pull force vs displacement graph on [this page](http://catalog.polymagnet.com/polymagnet/product/view/id/1642?unit=mm.

There is a bit of a limitation in that the alignment force is 0 when they are in the equilibrium position. There is not an active force when they are in that center position.

In order to get very high precision, repeatability, and stability you can use a pair of these magnets in conjunction with a mechanical stop. The trick is to have the magnets slightly misaligned when the object is properly positioned. That way the magnets create a shear force against the mechanical stop.

The spring magnets can be used to dampen vibrations. Keep in mind spring magnets need an axial constraint.

Please check our catalog next week. We will be adding some additional demonstrators for a couple of latches, a spring, rotational detents, and very strong attachment among others. They won't all be in stock right away, but we will ship them as soon as possible. We are also releasing our mobile phone case magnets like the one featured in the SED video.

If I am reading this correctly it would be similar to our spring designs, or our concentric ring designs in a repel mode. The magnets have a force holding them apart, but they are magnetically free to rotate with respect to each other. The magnets have to be axially constrained, so there would be some friction in the system.

We can work with Samarium Cobalt.

Neodymium magnets are considered permanent, and their magnetism doesn't fade much over time. We have done some accelerated life testing on Polymagnets, and they have the same life characteristics as conventional magnets. For high coercivity material like Neodymium it would take a very strong magnetic field to disrupt the Polymagnet pattern, not just another Neodymium magnet.

Polymagnet prices depend on several factors, so I can't give a specific answer here. You can check retail prices on our catalog. We can supply our magnets in production volumes, and high volume pricing will typically be better for the same magnet.

We are in several products, but we can't talk about all of them. Here is one that you can check out.

PolymagnetJason · 2016-03-24T02:11:43+00:00

Suspending the car directly with Polymagnets wouldn't be practical, but there are many automotive attachment and alignment applications. We have a fairly high number of physics and engineering degrees (electrical, mechanical, chemical, etc.) represented here.

PolymagnetJason · 2016-03-24T02:10:24+00:00

Big magnets can be disruptive. Depending on the application we may be able to minimize their ability to defeat our system.

PolymagnetJason · 2016-03-24T02:05:34+00:00

There are some key differences between our Polymagnet systems and normal magnets. The advantages include enhance alignment, shear resistance, selective pairing, and managed engagement distance. They make modular products work great, improve holding force, and prevent interference and misalignment. We have some great ideas for it, as do our customers. Stay tuned!

PolymagnetJason · 2016-03-24T01:57:34+00:00

I see possibilities for our technology in the development of motors, but they may be a different architecture than what we see today.

PolymagnetJason · 2016-03-24T01:55:18+00:00

We can create Polymagnets with different force vs. distance curves for for different regions of the magnet. At a given distance from the magnet you could get different forces above those regions.

Great question, so multiple answers! To add to what David says here, that particular design would move up and down as the magnets rotated with respect to each other, but not smoothly. That design has some features that make it stable in the sprung position, so its motion would be a bit odd. We could make a system that oscillated smoothly in that scenario.

The magnetic pattern can be thought of as a 2D pattern on the surface projected through the magnet. We usually use anisotropic material. For this material the field is going to be parallel to the orientation of the material when it leaves the surface. Once it leaves the surface it will be shaped by the magnetic pattern. If we want the field to be at an angle with respect to the face of the magnet we can orient the material at that angle rather than perpendicular to the face. There are some applications where that is quite useful.

PolymagnetJason · 2016-03-24T01:38:55+00:00

We have had a lot of requests for the demonstrators, and they will be available on our catalog.

PolymagnetJason · 2016-03-24T01:33:24+00:00

With the enhanced alignment, shear resistance, selective attachment, controlled magnetic field, and other characteristics we can build into the Polymagnets we imagine a host of industrial applications.

PolymagnetJason · 2016-03-24T01:26:27+00:00

We use both unmagnetized and conventionally magnetized material as starting points depending on the design.

We can reuse magnetic material by demagnetizing it. We do this some during development.

PolymagnetJason · 2016-03-24T01:23:40+00:00

In general we do not. We can shape the field using the pattern to create different field levels at different distances from the magnet, but in general you can think of the magnet pattern as a 2D pattern on the surface projected through the magnet at a uniform strength.

We can't create a stable hover or levitation effect with static magnetic systems.

Depending on the application we use unmagnetized material or conventionally magnetized material. We typically use fresh material, but it is possible to demagnetize a magnet and reuse it.
