    Nice one ! :) I used the 3x2 N35's in my Valk which have a pull strength of around 2kg less than the N38's, and I think they are too weak in the Valk. I do like the Valk M though it has been made better IMO, but it could be a bit better :)

    Here is an online calculator for determining magnet pull strength ... https://www.kjmagnetics.com/calculator.asp

    I found that sliding the magnets across each other as the easiest way of separating them. They split easily. I've used Superglue because it's easy to apply and the initial contact sticks quite quickly. It does take a while to dry completely but seems to do the job.

    Probably the biggest thing I've found is organisation. When I've had everything organised ITO parts and process the entire process flows nicely and can get done quite quickly but effectively.

    I did my Blue a few weeks ago. I used N35 3x2mm on the edge pieces and N35 4x2mm on the corners, with only 3 magnets in each corner like in a 3x3.

    It turned out awesome IMO. If I hadn't put magnets in my WuQue I'd be using the Blue M as my main for sure, no doubt.

    Idk how it feels in the valk, but N35 4x2s are really faint in my Yuxin blue. Also, get weaker magnets for the inner layers because those magnets will be double the strength as normal to accommodate for parity

    Hi!
    I'm going to try making magnetic cubes, and I'm going to use a weilong Gts and a kung-fu 2x2.
    I think I will go for n50 4x2 my for the weilong gts and don't know what to use for magnets for the Kung Fu 2x2? What magnets do you recommend? I thin I will be using n35 4x2 mm:)

    Hi, I would like to put magnets in my wuque. Do you have some detaild instructions which magnets and where to put theem? I have never done it. I would also like to put them into my valk3 stickerless. So, i get them on ebay? I guess gorilla super glue would be ok?. How do you know on which exact spot to put them?
    Thanks for any info

    There are already a few tutorials on YouTube on magnetising a 4x4. For reference search for DMCubing and SpeedCubeReview. DMCubing has a bunch of tutorials on putting magnets into various 3x3's and has a good process and method which is what I've been using. SpeedCubeReview has done some videos on putting magnets in larger cubes including 4x4.

    I used Taco Cuber's tutorial for magnetizing the WuQue.

    I ordered 500 4mm x 3mm N35 magnets from an eBay seller that I have used before but I have received 500 3mm x 5mm which are useless. Very annoying.

    Has anybody noticed what might appear to be counterfeit magnets hitting the market?

    Daily, I receive comments on my videos from people saying that either they've used N50 4mm x 2mm in cubes like the Air or Valk (which if they were true N50s would result in a terrible feeling cube), or the N50s which they received were nearly unnoticeable in cubes like the GTS or Thunderclap V1.

    It's a daily thing for me now to get comments like this and it leads me to believe there are a lot of sales being made where the quality and grade of magnets is being misrepresented, where N35s are being passed off as N50s.

    Seems like a lot of these are being purchased on eBay. Then yesterday I get a comment from a fellow who says his Valk is ruined because he used "N35s" in it. So in his case, his N35s were overly strong.

    Fwiw, the best companies I know of are apexmagnets.com for the 4x2 N48, thethackery.com for 4x2 N52, and gaussboys.com for 4x2 N38 and N42. Gaussboys are extremely high quality mags, their gold plated N42s (which feel like magic in a Valk, btw) are jewelry quality- the most beautiful magnets I've ever seen! Apex mags are great but you need to catch them on a weekend when they offer free shipping, and Thackery is extremely efficient and the quality of their magnets is top notch. Occasionally I'll use magnets365.com (a Chinese company with a US ship-from address) for 4x2 N35- they're ok quality (not the quality of the others I just mentioned), but they're consistent and work perfectly in the Air, Valk, some 2x2s and others. And recently I placed several orders with Chinese companies to try out some hard to find sizes like 3x2. Still waiting on those....

    I tend to always order in minimums of no less than 500 magnets in order to save on shipping, etc. I realize that's a bit overkill for the casual magmodder.

    I don't think I'd recommend using eBay. I think you're better off dealing with a reputable magnet company that you can call up and talk to. If you're really into making a decent high performance cube, why cheap out with the magnets? I don't think it's worth the gamble.

    Thanks for the write up @DMCubing , I took a gamble but I just ordered 100 4x2mm gold plated N42s from gaussboys to try out in probably a Thunderclap before moving on to the main show, my GTS, if they work well. I read every single post in this thread and gathered N35s are generally too weak, N50s are usually quite strong, and N38s and N42s are relatively common middle grounds, however it is of course up to personal preference and what cube you use and the thickness of its plastic makes a big difference.

    Hype.

    I think you've made a good choice. They'll work nicely in the Thunderclap.

    Exactly. It really comes down to personal preference. I love the N42s in the Valk and I prefer both the N48 and 52 in the Illusion GTS.
    I'm looking forward to hearing how you like the Thunderclap V1. I've made two, one with N48 and the other with N52. It can handle the stronger mags pretty well. I haven't tried the N42s in it yet. I might. I've got an extra one that hasn't been magnetized so I might do that when I get a chance.

    You'll love those N42s from gaussboys. They're almost too pretty to use. Seriously, jewelry quality.
