Diametrically Magnetised N42 Neodymium Magnet for Reed Switches, Rack and Pinions, Shafts and to Provide Rotational movement - 8mm dia x 1mm thick - Pack of 10

Very good quality magnets. I use mine with a self-adhesive magnetic foil to attach a piece of a paper or cardstock and keep it in place. They are very small, therefore thay can be removed easily.

Really weak. Bought them to magnetize and transport some miniatures that are a few grams a piece and it take around 5 magnets to get them even remotely sturdy.

Not very strong magnetic force.

Very weak and definitely not really N42, I have N35s that are a lot stronger than these

Bei den Massen steht 25x10x3 was bei einem rundem magnet ja nicht sein kann, also bestellte ich in der Hoffnung, daß der Durchmesser 25 oder 10x3 beträgt. Die magnete haben einen Durchmesser von 8mm und sind 1mm dick. Gehen wahrscheinlich wieder zurück.

مغناطيس قوي لكن حجمه صغير جدا

Rien à redire Taille conforme Fonctionne très bien Quantité conforme

Son del tamaño de una pila de reloj, ojalá los encontrará más grandes. Las dos polaridades por cada cara

The magnets are diametrically magnetised. That means they can be used for position measurement with for example an AMS5600 sensor. However the magnets are pretty weak and you must be closer than 2mm with the sensor.
