Small Magnetic Field Paper for Science, Education, Experiments, Students, and Teachers - 50mm x 50mm - Pack of 10

This is an interesting way to view magnetic fields. It would make an interesting teaching aid.My only slight criticism is that the image is slightly dark (low contrast) so it needs to be viewed under fairly bright light, but otherwise it is quite clear.

ordered it to reveal magnetic field of some tech gadgets, just for fun onlyit arrived in a cardboard postal envelop, inside packaged with a zip bag, i was quite surprised with its actual size and thickness, i knew it’s 5cm x 5cm before ordering it, just realised that it’s so tiny and flimsy when holding it, it will definitely go into bin if my wife found it on the floorit works as expected, clearly shown magnetic field on any surface with magnetic, but its tiny size couldn’t fully reveal everything even on small size gadget, i believe the 10cm x 10cm model will be more usableanyway, this product works as expected, i’m happy with it, would recommendhope you find these information helpful

As a motor mechanic this is very handy to have in my tool box as the magnetic rotor for the ABS is now built in to the bearing seal. Very easy to find what side of the bearing should face the pick up.

Small and thin, but works as expected

Small, very small.One side is rough.It’s a badly cut piece from a larger sheet - very uneven - so 0 for result, 5 for effort .Meh.Works, but it’s too small for any real use

Why did I buy it? Yes it works. It's a thin plastic sheet that displays magnetism. It’s just as described. But I played with it for maybe 10 minutes tops. That’s over a pound a minute. I can’t imagine I will ever need it, even though when I saw it I just had to buy it. The novelty interest is of extremely short duration. I cannot think of any actual use for it going forwards. It will probably stay in a drawer for ever. So be warned folks.

This film works very well for e.g. seeing the surprisingly many magnets on an iPad. The film seems a bit fragile, so I laminated it in 4x6" hot lamination pouch, with apparently no ill effects on the film or its ability to detect magnetic fields.

Vor dem Bestellen habe ich hier in den Bewertungen gelesen "Keine guten Abbildungen. Alles verwischt. Von den vorherigen Magnetfeldern bleiben Schlieren zurück" -- wär ja fast aus meinem Stuhl gefallen.Die Folie macht genau was sie soll -- es sind winzige Eisenteilchen enthalten, die sich bewegen und dunkle Linien bilden, wenn ein Magnet in der Nähe ist, sodass man die sonst unsichtbare Kraft des Magneten sehen kann. Dass diese Eisenteilchen in der Position verbleiben, in die sie das letzte Magnetfeld versetzt hat, gehört also dazu.Der Preis ist ziemlich stolz für ein einzelnes Blatt, aber es ist ja kein Verbrauchsprodukt.

La feuille est assez étonnante, je ne connaissais pas le principe très sympa de parcourir différents objets avec cette "loupe magnétique" afin de déceler les éléments qui composent un appareil électronique

I think it is not that good value for money.It works OK but not as sensitive as I had hoped for and it is quite expensive.

Arnaque! la feuille fait 4cm sur 4cm, inutilisable et en plus on voit qu’elle a été découpée au ciseau!
