FIRST4MAGNETS Small Magnetic Field Paper for Science, Education, Experiments, Students, and Teachers - 50mm x 50mm

Smaller than i expected but that’s my fault for not actually getting a ruler out 😂. Super cool great in schools, works great, amazing value for money

ordered it to reveal magnetic field of some tech gadgets, just for fun only it 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 floor it 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 usable anyway, this product works as expected, i’m happy with it, would recommend hope you find these information helpful

Very cool way to visualize the magnetic field of various magnets. There is a small flat magnet integrated into the packaging (a cardboard slip sort thing) to check it out initially. I wish I got a bigger sheet though! (but they are quite price so maybe another day!)

It works as expected. I wish it was a little bigger.

Very small but everyone loves the little show

Not really a gadget more a novelty but was cheap and nice to see positions of magnets in things like my Ipad Pro.

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 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.

Works well. Great for reverse engineering. Does not provide magnet strength, but size size position work well enough.

Good

Works exactly as described.

Does exactly what I expected!
