Let's hear your ideas for applications!
-
holding things together
-
Better motors, of course!
There's also "magnetic gearing" as a possible application, which would eliminate losses do to friction between gears.
Can also to make refrigerator magnets, and reusable car decals.

Superior tearaway pants, duh.
-
Being freespace in here... reactor containment.
From a professional view, all sorts of ordnance wizardry which would make my old profession a world of hurt. I fear for the EOD world of tomorrow. :(
-
Free energy, obviously. Duh. :wtf:
-
Holy shizzle that's cool.
Umm... better maglev trains? Superior electric car motors + regenerative braking? Magnetic transmission parts? Better power generation at any power generation facility? Finally, cost efficient fusion containment? A better MRI? A pocket MRI?
Not exactly sure, but I think anything that involves a magnet in its operation could get a boost (unless it relies on the conventional magnetic field and wouldn't benefit from the size or strength being adjusted at all).

Half the things you just mentioned involve superconduction and won't be affected in the slightest by any advance at all in permanent magnet technology.
Also now that I've watched the video I see that they have in fact just reinvented the Halbach array, as used since time immemorial to make cheap fridge magnets.

didn't know the name, but I was thinking the same thing while watching it, thought the latching seemed neat.

They did an AMA (https://www.reddit.com/r/IAmA/comments/4bns7f/iam_jason_morgan_vp_of_engineering_at_correlated/) on Reddit (and were still popping in to answer questions). Response: Halbach arrays take an array of magnet in a particular arrangement, and throw all the field/force to one side. What we do is design magnets to have really high strength in attachment, or magnet pairs to have alignment, shear, or spring behaviors.
Edit: In the case of fridge magnets, I think they just magnetize the strips by rolling them over a diametrically magnetized drum or rod.

He's right about how fridge magnets are made, but the reason they do that is that it creates a Halbach array which attaches much more strongly on one side, thus allowing the manufacturer to use a weaker, cheaper magnet.
