I really don't know. It looks like the sizes and shapes are the same, for the most part. The magnets are in the center of the sides with these, not on the corners, and the magformers have more rounded edges. My son has about 200 pieces of these now. Family members bought him a set with the led light and the set with 4 tires. I wish I could tell you if they'd work together.

Yes! You want "rare earth" or "Neodymium" magnets. They are STRONG and tough to pull apart. We like the 3/8 inch to hold 1-2 pages (B000E67ZO4) and the 1/2 inch to hold more/thicker pages (B000UCWU38). Good luck - and keep them apart on the board or they will "smash" into each other!

I'm not sure that this would be a good application for these magnets. The magnetic field produced is very strong, but decreases rapidly with distance. I would imagine that you would have problems holding them in place. I would suggest that you buy the contacts and install them according to manufacturer's recommendations. For example, one well-liked offering on Amazon is Interlogix Door/Window Terminal Contact, Surface Mount, White by UTC (Formerly GE Security/Sentrol). There are several alternatives listed. While it might be nice to engineer your own system, these contacts are inexpensive and easy to install. This, I believe is preferable to using these magnets. This appears to be a case of not reinventing the wheel.

They are magnetic. We use them in our preschool classroom for the kids to use with magnetic Alphabet Letters.

Yeah these magnets held up cardboard against my refrigerator, they may be small but their magnetism is very strong to other magnetic objects.

I tested your idea with different weight magnets (not a scientific examination of the possibilities, of course!) but, what I found is that they will hold the a magnet equal or slightly heavier than they are. This is basically the same as all the business promotion ones you get from companies hoping you'll stick their advertising or phone number to your 'fridge... all of those types hold just fine.

Yes. One magnet would probably work all by itself. I assume you mean ONE magnet on each corner for a total of four. They are really strong, so four would definitely be ok.

Probably not. These magnets are fairly weak. That is just my opinion, but I find these to barely be able to hold themselves to a surface, let alone hold anything.

If that metal base is considered magnetic, meaning it's made of iron, these magnets will work. They are amazingly strong, which is shocking given how small they are. To be fair, the magnets on the back of those letters rarely stick to anything. These magnets are small enough and strong enough I believe they will work well. I use them to make my own magnets and I'm often shocked by what they stick to. The issue I see, is that there is a warning on them. They are so strong they will snap together. Mine have never shattered, but I have heard they will. They are very good magnets, though. I would have given them more than 5 stars if I could have. :) Good luck!

My grandchildren have them. I really don't know. I don't remember a magnet on top.

These magnets are tiny but they are also strong. Direct magnet to metal contact on a model would not be recommended as these magnets do have some power. However, if you were to apply a barrier between the magnet and the metal then it would probably be okay.

I would assume. It just says "52 magnetic letters." I tried to return it, but Amazon said to keep the item. I'm donating it to our church's White Elephant sale, so don't want to open the package. Melissa & Doug has a website.

Yes they are great, even after my son throws them all over the kitchen. They have about a 1/4 inch magnet chunk in them.

Can't say for sure, but my guess would be yes since these magnets really are so very strong. These are not the same type of magnets you would find in a tourist trap when buying refrigerator magnets for souvenirs. These little suckers are much stronger

I have not had any issues with my set. I would contact Klein directly or an electrical supply may be capable of ordering the magnets.Good Luck!
