Ferrite Bar Magnet with North & South Identified for Science, Education, Experiments, Students, and Teachers - 16mm x 4mm x 50mm long - Pack of 4

I just ordered these for my year five science lesson. They are perfect. They are blue and red just like the picture, despite the fact that it says in the title that they are grey. And they are fairly strong. Certainly enough for my class. The sides repel and attract each other very well. I'm so happy with them considering that I've read reviews of other magnets which turned out to be rubbish. I would definitely recommend.

Bought for educational purposes and wasn't expecting too much, but these are really quite bad. I don't think I have ever left a one star review before, however this product is particularly disappointing. They have an incredibly weak magnetic field (I have stronger fridge magnets!). That in itself is not a major problem for me, but the paint is also flaking off. Picture attached to this review is exactly as I have received them.Update- I just dropped one on the floor (laminated floor) from waist height, and it shattered into two (new photo added). The edges are now razor sharp. Product is unsafe for children in my view and no good for teaching.

Two magnets arrived broken

Checked the contents on delivery. The magnet in the centre of the pack was broken in the middle.Weird don't ya think.These magnets are very thin, brittle and not very strong, anyway for the price I ain't that bothered.

Perfect for my Grandson who’s just started learning about magnetism in school.

very good quality

I guess you get what you pay for. Very weak magnets. Not really that good for showing kids about magnetic fields. Home schooling fail. My fridge magnets are stronger. At least they do show north and south and what happens when you put them together.

They are incredibly weak, rubbish.

Trop petit et trop faible pour des expériences de démonstration

Ich habe diese Magnete benötigt um bei einem Mähroboter die Pole der verbauten Magnete zu finden.Dafür sind sie gut geeignet, weil ich feststellen konnte das einer der Magnete falsch herum eingebaut war.Das war der Grund warum der Mäher oft in Störung ging. Die Kraft der Magnete ist aber ziehmlich gering, so das sie für Befestigungsaufgaben nicht geeignet sind.Aber zum Prüfen von Sensoren usw. sind sie sehr gut geeignet, darum gibt es eine Empfehlung von mir.

Sono debolissimi, not so much strong ....

diese angeblichen Magnete haben keinen Nutzen, da diese an keinem Metall bleiben, da das Metall fast nicht magnetisch ist!Irreführung?sehr bedenkenswerte minderwertige Ware
