Based on the size of the disc, would these be good for turning bottle caps into fridge magnets?

These are very tiny. I think they would sit too deeply inside the bottle cap for the cap to be used as a magnet with it's top showing. Stacking a few might work though.

No. Too small. Strong though. They are too thin or bottle cap. Could probably do it if you doubled it up or even tripled them by stacking .

Yes...have not tried that, but the magnets will work for that...Merry Christmas and Happy New Year....

Sadly no. I tried with both fridge magnets and some slightly stronger ones I use on spice jars that also stick into my fridge. It would be easy enough to magnetize though.

Magnets are not great for hardrives. If you have a mac book air you have a solid state drive that is not as susceptible as old school spinning disc drives. After several months we have no complaints.

I imagine with the plastic ends it will work fine. Currently I've been using the hammer with metal ends to break ice within plastic bottles on virtually a daily basis, works fine with no issues.

Yup! They're metal so they will absolutely work with a magnetic knife holder.

No. The caps slide into holes made for special bottles. They won't work on just any bottle.

No. The sizes are specifically for CD cases, but it would make a cover for a homemade DVD disk.

I don't know. I use them for yogurt pops and smoothy pops. I think the top of the frozen pop would be a bit big in diameter to use in a water bottle.

If there is a magnet attached to them yes. It's not strong enough to hold the bottle caps on their own

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

Not very. I purchased these to hold a dry erase board to the fridge. These were not strong enough to do the job (even using all of them to cover the back of the board).

Not very well. These are made to fit a can and are very loose when used on a 12 oz. beer bottle.

They may be a little bulky for small computer screws. However if they are able to grab them, it would be able to remove them.

It depends on how much weight you are going to have in the jars. they will support the jar and probably an ounce or two but not too much more than that. You will want rare earth magnets.

Good question. I will conduct an experiment and let you know. I don't know how strong these are in quantitative terms but they are pretty damn strong for such tiny magnets.

I believe the smaller two would work for filling roller ball bottles. The smallest one is quite small.

The magnets you would use to attach this to a refrigerator are neodymium ring magnets like these 10 Neodymium Magnets 3/4 x 1/4 x 1/8 inch Ring N48 or these 10 Neodymium Magnets 3/4 x 1/2 x 1/8 inch Ring N48. You can also find bar magnets with pre-drilled holes but they likely will be too large and stronger than you want for this purpose. Two things you should know about these if you have never used rare earth magnets: first, they are far, far stronger than any other magnet type the average person has come across in their lifetime and can easily injure yourself (I have used the first size linked above and had several blood blisters and pinched the skin off my fingers to prove this is true). The other thing to know is that like much weaker ceramic magnets, they are brittle and you cannot easily drill your own holes in these without them crumbling apart. That is why you need the ring magnets instead of disks (unless you can insert the disks into a compartment or internal space without using a screw) for the knife holder. The ring magnets are also more versatile and fun than the disks since you can stack the left over ones on a straw and watch them float three or four inches apart. Lastly, brass screws will not be magnetic and easier to use with these.
