What And Why they made this strong magnets for ?

There isn't one specific reason for it that I know of. I can think of a thousand different experiments and fun thing to do with it. YouTube it!!!! My only problem was finding a safe place to store it. I have used them to pull metal shavings out of drilling fluid also.

There are three disc shaped magnets inside that are glued 120 degrees apart from each other. I'm not sure if they were rare earth. Although, I did replaced mine with a large ring shaped neodymium rare earth magnet that I purchased from magnet4less.com and it has a much higher pull-force. They are not cheap though.

Not sure what you mean. They are big circles with magnets on the outer edge to attached to each other

Magnets don't have the same effect on aluminum, fun fact if you have enough aluminum a strong magnet will actually slow the movement down instead of a force to bring it together. If you were to drag a powerful magnet along a bar of aluminum there would be resistance, I believe its an electrical force but this is very old stuff for me I can't be sure.The top clip part however looks like stainless steel and magnets will most definitely work.

The magnets were used to attach tracking device to undercarriage of automobiles. I didn't use screw's, but magnets work great!!

there is no magnet as far as I can tell . It just means it "draws" insects to the trap. Not sure the other answers were from people who have used this product. Sounds like guessing to me. I have used them for YEARs and have never seen a metal magnet. Kind of makes me laugh to read the other responses.

I'm not sure what magnet you are talking about - I don't think there's a magnet on this.

Good question. I just tried some magnets and none of them stuck. So it seems whatever it is made of is not iron or steel.

I don't know enough about electromagnetism to answer this, but it's pretty freaking strong. I have to wrap it in a crazy amount of bubble wrap and then into a box to keep things around it from sticking. DO NOT PUT IT ANYWHERE NEAR ANOTHER NEODYNIUM MAGNET. They love each other, violently. You will bleed.

These magnets were pretty strong. They may be too large in diameter to use on a name-tag. When I stuck two together without the spacer, they were incredibly hard to separate. I would recommend a rigid backer for the name-tag (otherwise you may get too much flex and peel on the edge of the magnet, between the magnet and the cloth (as you pull the tag away) and end up "peeling the magnet" off of the cloth. I used these to actually glue to another, weaker refrigerator magnet I had. I found the poles and got the strongest side to the refrigerator and used a surface insensitive super glue to bond them together. Since I don't take them on/off the fridge a lot, it seem to be holding so far. You may be able to use a hot-melt Hobby glue from Michael's too bond to the cloth, but I might suggest using the smaller, 1/2" version of these. I believe I've seen plastic tags that actually have a "Magnet Bar" with two 1/2" diameter magnets glued to a piece of metal and then the plastic piece has a metal bar glued to the back of that. When you wear the name tag, the magnets get "Sandwiched" between the two pieces of metal but the way they are attracted, the metal bar acts kind of like a "handle" when you take it off. If you search "Magnetic Name Badges" you will probably be able to find a picture of what I'm describing.

It is a piece of metal that magnets stick to. Basically they are small magnet posting boards, with cork on the back.

I think these magnets are too thin and small for your project. I have already shattered one by having it clash against another stronger magnet.

The magnets are really strong. I've had mine about 4 months and it's fine so far.

These magnets are a bit more expensive than others, but they are well worth the cost. Not only are they very strong, but they will stick to anything, including unfinished wood. As a matter of fact, make sure that you have them positioned properly before you place them, because once there they are applied, It's almost impossible to pull them off to reposition them.

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!

They are metal and a magnet will hold it. I actually just checked out of curiosity due to this question.

I don't understand what the point of the magnetic flap on the cover would be. Perhaps you could offer your thoughts? The magnets are on the casing itself, and the entire outer segment of the cover is a magnet. The cover closes very securely without issue when these two meet.
