FIRST4MAGNETS Medium Magnetic Field Paper for Science, Education, Experiments, Students, and Teachers - 100mm x 100mm

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 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

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

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

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

Very small but everyone loves the little show

Just what I needed to visualise multipole magnets, and the field around magnet interation - attraction /repulsion. Comes with a test magnet multipole, this is usefull for explaining to others the concept of mulitipole / correlated magnets. Paper is like photo film in stiffness will bend round a radius of 5 mm smaller radius are no big problemshowever as lose contact is not nessesary and air gap of 0,5 - 1 mm is ok. For my use (analysis of magnets 2-3 cm in size - on occasion up to 10 long) I see no need for a larger paper size. even with larger magnets the paper may be moved around. The larger size might be usefull when photgraphing or large magnet arrays. I think there would be no problem cutting a large piece, with paper scissors or simalar. Even just 'playing around' (I used it on preety much all the magnets I have) gave some suprises, even a fridge magnet can have two or more poles...

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!)

Good

Works exactly as described.

Does exactly what I expected!
