how strong are these magnets?

I would say strong enough to hold when full of binder clips, paperclips, or other objects that might have some heft. Strength in magnets is a little hard to measure for these, but I use mine for a spice rack and I never worry about them falling off, even when nudged accidentally. Hope that helps.

They seem to be very good. I have them hanging on the door of my pantry and have not had any mishaps yet with any of them falling off when opening/closing the door.

i use these in my camper on the stove lid and they really hold tight even when the lid is open at a 45 degree angle . i think they are a really good product

The magnets are really strong. I think they will pull off the glue. You can try stronger glue, but even then I think it's a matter of time before they pull apart. It may also depend on the size of the magnet. The larger the magnet the stronger they are. The tiniest magnets may not separate from the glue.

Not terribly difficult. The key is not to pull them straight off, but to tip them on an angle and pull, or slide 1/2 off the surface and pull. Also depends on the magnet strength - obviously the 80lb's are tougher than the 40lbs! I weigh only 155lbs and I have no trouble.

Yes the magnet is very strong, your not going to have any issues with it falling off.

These have a 1.6 lbs. pull force in ideal test conditions. They are N42. Know that the higher the N# the more fragile the magnet. The magnetic strength per weight can increase but with that they increase in brittleness, they can break to pieces much easier. N42 provide the magnetic strength with durability for the best design for craft magnet uses.

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.

We bought this as a gift for our son-in-law last Christmas, so we really couldn't say what the magnetic strength is on it. Sorry!

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.

They seem pretty solid. You'll probably strip the head off the screw before the screwdriver breaks. They're also magnetic which is a plus.

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

these are magnetic and stick together, so far I have not had a problem with my jewelery falling off. I use them on my costume jewlery. If it's a valuable piece I would order the larger magnetic locks. I have ordered a few that are flat and about the size of a dime. They hold very well and have larger magnets, and are stronger.

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

they are pretty strong, approximately 1/2 inch thick. I use them pretty much everyday as I have granite countertops.

Yes, the magnet is pretty strong. Only issue I had was keeping it clued onto a wood surface. Can't speak for other surfaces but if I had to guess on a plain wall iy should be fine. Hope this helps.

These are pretty powerful magnets.. The magnets are at my grandson's house and I could go over tomorrow and check it out for you...

I'm afraid it depends on the strength of the magnet. A decent magnet should.

The magnet is fairly strong. I wouldn't chance it. I might carry it separately if possible
