MIN CI 100 Pcs Strong Neodymium Magnets Disc, 8 x 2mm Small Magnets for Whiteboard, Mini Round Rare Earth Magnets for DIY Building Scientific Models Dry Erase Board Office Fridge Crafts

What can I say? They stick to metal. That's what they are supposed to do, and they do it well. For their size, they are incredibly strong. I use them to stick photos, posters, banners, etc, to the metal cabinets in my office.

These magnets are super small. I almost didn't believe it was 100. But it was! I wanted to use them for a magnetic marble drop for my daughter's birthday party. I tried other magnets, with no luck, and this was my last hope before I scratched the dream. Happy to report that it did work, when no other magnet did. Slide resistant, but easy enough for kids to remove. Sleek, silver and tiny but mighty.

I thought people were exaggerating when other reviews mentioned how strong the markets are and that they would pinch your fingers. Nobody exaggerated. I am using these on a magnetic white board at work, and they work very well.

I bought these magnets so I could hang some decorative tins on my wall. When I took them out of the box and tried to pull one off the roll, it zipped back to the roll and broke the magnet it hit. The magnet just shattered into 3 pieces. So my recommendation would be to be very careful that you don't bang the magnets together too hard. They might shatter. Overall they worked very well for what I needed them for.

Strong, thin, flat magnets, easy to use but with a strong pull and hold. They look great too!

I love these magnets !, received a small cardboard box that held the magnets within a protective foam wrap, so they all came unharmed :)These magnets are pretty powerful but not hard enough so they don’t separate with a moderate amount of force. I can put one on the top of my hand and the bottom and they gently hold on both sides. I’m using this on a craft project of mine and through the fabric and foam I put between them, they can hold up pretty well !Advice I’ve gotten tells me that stacking the magnets before Installing them causes them to be more powerful so I will be trying that soon !, so far as gluing goes, hot glue works and won’t come off because of the smooth surface, but can be removed with some time scratching, though I’m comfortable enough that these will hold up on my project for a while so I don’t worry about it !I would advise you not to get these if you’re planning on letting them ram into each other from a distance because they will crack !!, the thin shape of this and it’s power makes that inevitable but I’d like to point that out for anyone needing this for that reason :)

They are very strong little teeny tiny magnets they are way smaller than I thought they were and while adorable are kind of useless for what I need

The magnets came on time and were well packaged. We use these magnets to detect vibration effects. I use a coil of wire of around 200 turns on a 2 inch diameter, 2 inch long coil form as an electrodynamic vibration pick up. That is, try to measure the EMF (voltage) generated in the pick-up coil. If you are into guitar pickups or just enjoy observing Faraday’s Law of Induction in action, you will enjoy using these small but powerful magnets in all kinds of experiments. For instance, push or pull the magnet into the coil or out of the coil and monitor the current pulse that you can detect by connecting the coil end wires to an oscilloscope or a good quality galvanometer. Stack the magnets to make a stronger magnet. Try to suspend the magnets from a light string amd bring some other magnets close to the ones suspended in the air. Places some magnets on the underside of a thin sheet of clear acrylic and place some iron filings on top of the sheet. Have fun and enjoy your magnets.
