Magnets Discussion and Help thread

[AidanNoogie]

It's hard for me to upload a picture, but I'll take a shot at a diagram. This is if you look at each edge, from one corner to another:
3x3:
| +|- | |
| | -|+ |

4x4:
| +|- -|+ | |
| | +|- -|+ |

5x5:
| +|- | -|+ | |
| | +|- | -|+ |

6x6:
| +|- | +|- -|+ | |
| | +|- -|+ | -|+ |

7x7:
| +|- | -|+ | +|- | |
| | +|- | -|+ | -|+ |

Does that make any sense? I've never done a 2x2, or anything bigger than a 7x7, but if you can figure out these chicken scratches you should be able to magnetize any size cube. If you'll note, a 6x6 is basically a 4x4 and a 5x5 put together.

Maybe you could email me a picture? I'll PM you my email address if you want too.

I've tested this. The notion of assuming that enough glue will end up under the magnets by placing the glue last is false. The extremely thin layer of glue that you'll end up with won't be strong enough to handle the rigors of cubing. You're better off having a little glue under the magnet, then over the side and top of the magnet. The idea is to have the magnet encapsulated in glue. Some people are very hard on cubes, slamming them down onto hard surfaces. You need your magnets glued as best as possible.

It's also advisable to use a cotton swab and clean the factory lube off the interior of the cubie pieces with rubbing alcohol. This improves the bond. There's more lube inside the pieces than you'd think.

I often score (scratch and rough up) the areas where the magnets are placed after I've cleaned the lube off to improve the bond.

As carefully as I am with gluing, I've still had people loosen a magnet in one of my cubes.

I've never put glue under the magnets, mostly because I'm lazy in some respects, and just put glue over the magnets. I've done a fair number now, and have also removed some magnets to put other magnets in and the 2 that I've done have been a small mission to say the least. Those magnets are stuck good and well, so much that I've ended up damaging some cubie pieces trying to take the magnets off

I'll draw up a picture and figure out how to upload it later today.

Let me know if this works and the picture makes sense:

Note that the corners in the Yufu are not magnetized (orange ink denotes what it should be if it were magnetized), and the polarities in the G6 are slightly different from what is written. The way the G6 is and the way it's written both work, but what is written will make it slightly easier to place the magnets.

This looks very nice, but a question: here at Johnny's Wushuang image the polarities should follow in Line NSNS.

I've done 2 5x5's so far and I've used the same configuration for both as in the attached pic ... They both have turned out quite well.

Edit: for each "line" the polarity travels in the same direction

On your image, I noticed they are going NS SN.( thats how I did it). I know it both works, but which do you think is better?

I don't think it matters for odd-layered cubes, because the distances between the non-adjoining magnets are large enough that they barely interact. I am intending to magnetize a yuxin 5x5 at some point, I might just pick up 2 and try it both ways just to see.

Thanks, so which magnets do you recommend for Qiji Wushuang 5x5? Did you like the" 4x2 n35 for the outer layers, 4x2 n38 inside" combo ? I also want to try qiji 6x6 and G6. should i use the same combo?

The 4x2 n35/n38 combo is a good balance, in my opinion. I find the Wushuang (and this may just be the puzzle I got) to be a little gummy. Otherwise it's really good. If you want a subtle magnetic feel you probably want something lighter, as this is fairly pronounced. On the last two 6x6s I've done I've used the the 4x2 n38 between the inner and outer wings. I used 4x2 n35s between corners and outer wings on the G6, and approximated that strength with 4x1.5 n38s on the Yuxin Red because 4x2 were too big to fit in the corners. Since the inner slice is doubled you definitely want something weaker there. The G6 I used all 4x1 n52s, and I thought it came out a little strong. I used half and half 4x1 n52s and 4x1 n38s on the inner layer of the Red, and thought that was a pretty good balance. I've never done a Wuhua, so I can't say for sure what will fit there. It is on my short list of cubes to magnetize, though, once I sell some of the ones I've already done and have some money to spend on cubes and magnets. If they'll fit I'll probably go with the same magnets I used in the Red.

I put n38 4x1.5mm in a Warrior W and it is a my main. It may be a bit weak strength for most, but perfect for me!

 

[NewbieCuber]

I just magnetized a YuXin Little Magic 3x3 with 4mmx2mm n50 and the lock feel is quite pronounced. I've order some weaker magnets to try it on some other cubes. I think the n50 is probably a bit too strong, but dang, it is super stable.

I used N35 4x2 in a GuoGuan Yuexiao Pro (which has magnet slots, which is nice and makes the whole process a lot faster). It gave a very subtle but still noticeable result.

The same N35 4x2 magnets are very strong in a 2x2 (MoHuanShouSu Chuwen). So strong that I think about ripping them out again and using weaker ones. What magnets could I use that feel maybe 30% weaker? How do N35 4x1.5 magnets compare?

Edit: I used the K&J website and if I did it correctly, 4x1.5 are 15% weaker and 4x1 are 33% weaker. I think either would be a improvement. Now the real question is: do I rip out the magnets or do I order a new cube?

I ripped about 25 magnets off a cube, I used nail polish remover that set for a while. It wasn’t that hard. It took me about 20 or so minutes. Be aware that I did have to throw some away because they were chipped and they wouldnt lay right. Good luck!

As someone with (unfortunately) a lot of experience removing magnets, the way I've done is to soak the pieces in hot soapy water overnight or for a few hours, then ply them out with a screwdriver. Then repeat for any stubborn ones that are left. The magnets will still be usable as well

I used 4x2 N35 in my XingHen and it was too strong so when I got my ChuWen I used 3x2 N35 and it's so much better.

What’s in the cubicle Chuwen and XingHen? Thanks

 

[Cubing 101]

does any one know the magnet size and strength in the SM?

 

[CornerCutter]

I'm positive that SCS uses N50 3x1.5mm magnets for the Chuwen 2x2. I have those in my Chuwen and they are great!

 

[Ghost Cuber]

3x2 N35

There is lube in the Cubicle ChuWen and XingHen.
