Jesus christ, I don't even want to imagine how long a 13x13 would take.

Well, it's easy enough to figure out. First, calculate how long it takes to solve the 13x13, then add how long it takes to assemble a 13x13, then finally, multiply that time by the square root of infinity and you find that you are going to be putting magnets in Rubik's cubes until the universe implodes.

I thought the universe was going to expand until it reaches heat death? Maybe beyond the scope of this thread. Either way, at the end of time, Chris would still be gluing magnets

How many pieces would actually have magnets? Would the physical size and distance between magnets make it more difficult or less effective? Just curious, I am not thinking of doing it :)

Here are some of my findings from my research and experiments.

Except for the centers and obliques, all edges and corners would be magnetised, and for best effect, the core and large edges should also be magnetised.

Since you asked about distance between magnets, here are a few factoids:

Magnetic force is a squared function, which means that plastic thickness has a VERY SIGNIFICANT EFFECT on the pull force, and torque required to make the turn. This is part of the reason different cubes require different magnet strengths, because plastic thickness varies so greatly. When it comes to handfeel, it's a pretty narrow strikezone for optimal conditions! For the Cubicle Labs line of puzzles, I've tested a variety of magnets to find the best per each puzzle.

Since the radius from the center is much larger, the torque required to make the turn is also affected, which is compounded with magnetic force, so the size of the puzzle does indeed have an effect on which magnets are used for effective speedsolving.

EDIT:

A magnetic 13x13 would take at least 276 magnets for the minimum effect.
Which is actually humanly possible, I could actually make one of these for science!

I've made 3x3 cubes with 72 and 96 magnets in different patterns of repulsion and attraction to test, and 276 is actually doable in about two evenings or so.

@4Chan, a few years ago the magnet idea was bounced around on the forum and the observation was made that having magnets attract through adjacent corners and edges would only have a small component in the direction of travel, probably not enough to win over friction when the pieces are almost aligned. The larger component would be pulling the surfaces together (increasing friction anyway). It was speculated that having corners and edges repel would be interesting because the larger component would push along the direction of travel while there would be a smaller component pushing the pieces apart. Did you try that?

I've done a few experiments with repulsion, and although repulsion does "push", you have to surmount a barrier to turn past the repulsive force initially to attain the "push. So to get a hypothetical .5 newton of force, you have to apply at least .5 newtons of force to get past the magnet initially.

I tested different angles and pieces, and found that no matter how it's arranged, the repulsion creates "dead zones" within the turn which make an awkward feeling puzzle, especially during LL algorithms.

From that, I concluded that attraction is the best way to go for speedsolving.
Every night, when I'm not making batches of cubes, I'm doing various experiments with different arrangements and puzzles, and perhaps soon, I'll experiment more with repulsion!
 
Just to shout out here, if you haven't seen the Cubicle.us thread:

I will be giving away seven magnetic cubes for the 5-year anniversary sale!

There will be 5 Weilong GTS M cubes, one of my magnetic Gans Air prototypes, and a Valk M with the same radius/strength/arrangement as Mats Valk's tester cube!

The Valk M and GTS M cubes will be lubed and stickered to your preference, but the Gans Air will be one of my own personal creations, with multiple hours of modding applied to it. I really hope the winner of this one appreciates it!

The Gans Air M Prototype has rounded corners to the same shape as Weilong GTS corners so it doesn't have the catching issue, and has been completely weight balanced by removing all screws and internal plastic inside the pieces. It will also feature blue GES springs, which I find are the best, and will be stickered to my colour scheme.


All you have to do to win is make a purchase during our 5 year anniversary sale!
We will pick 7 random lucky people to receive the cubes!

I HOPE YOU LIKE THEM!

I have an order from the cubicle that hasn't shipped yet, does that count? I'm guessing no.

Just like we did with the Labour Day Sale, we can apply a retroactive discount!
Just message me your order number, and I will go ahead and do that, as well as put you into the raffle for the magnetic cubes!

Thanks! Just messaged you. As I said in the message, I only want entrance into the raffle, as I already used a discount code. Another question, do multiple purchases mean multiple entries? Or is there a limit?

Hmmm, technically speaking, multiple orders would be multiple entries.
Hypothetically, if someone made several several small orders instead of one big order...
