Do some tiles reverse polarity? Are all surfaces magnetized?

Some of the tiles do seem to have the polarity reversed. The end effect is that they don't stick properly to other tiles (repels them instead). Have not seen this problem with the original magna tiles nor another "off-brand" copy called Picasso Tiles.

The edges have small rectangular magnets in them. The flat sides are not magnets., I feel like the polarity in mine have changed - or they weren't all constructed uniformly, but usually switching tiles or flipping it over fixes the problem. Overall, my kids love these, but they do require a gentle touch and some patience.

Yes, it is magnetized. It will stick to any symmetrical end-surface properly as long as that surface is ferrous. If you don't mind that much money for a little convenience, it will work for your application.

Yes they are magnetized. I disagree with the answer from Goebel above. Maybe he got a bad batch.

The base is magnetic. This product is cheaper at newegg.com $98.99 w/free shipping.

I'm not sure what you mean by this. The puzzle consists of Tetris like pieces. They are not magnetic.

Yep it is magnetizied...this set is great...I own a computer repair shop...this is the only set I have had to use.

No, the board is not magnetic and the base does not rotate. I bought it as a gift so can't check on the cards, but the whole thing is quite good quality, so I don't think the cards are thin paper material. Everyone who has seen it loves it.

Hi, I don't know what Magna Tiles/Picasso Tiles. Yes, magnets lineup. Very powerful magnets. We are happy. I suggest to check out the YOUTUBE for all the combinations you can do with Magformers. I made my decisions after I saw it on the Youtube. I hope it helps. Myra

Make sure the polarity is correct. The negative pin -- Is marked on backside.

It's the polarity which is reversed and don't ask me to explain that. I finally gave up and started using batteries. It works fine and the batteries last a pretty long time. Good luck.

No. Believe it or not it's a lightly textured metal plate. Thought it was just plastic at first, but I tested it and the surface is magnetic!

I don't see any mention of "reverse polarity" in the product descriptions. Works fine in my airplanes.

Polarity should not be an issue. Also these are probably a little large for an instrument cluster.Check for cross reference guide for what you have now.

yes, it is magnetized. However, it didn't stick very well on my dishwasher.

Yes, they are in reverse of each other but the polarity remains the same. Also the polarity is clearly marked. I would also recommend a swaging tool that mounts in a vise and also sold by Amazon. The tool provides the proper amount of squeezing.

I cannot recall if they are magnetized. But, they didn't work well for me. Got I screw out but not the other.

No, They are not magnetized. Nice set of tools to have for RC Trucks and cars.
