Review: I had been looking at this magnetic viewing paper for some time as I had an application that would benefit from viewing magnetic field. At first I was put off by the price as $50 is a lot for a 4 inch square of paper but I was also intrigued by the fact that this paper contained colouration to depict different magnetic fields. I decided on this paper, the more expensive option, and hoped I made a good decision. This magnetic viewing paper works great. I am happy that my copy doesn't have the border as shown in the images - mine looks like it is just laminated - which aids in my application of the paper. People that I show this magnetic viewing paper to are amazed on how well it works and how it seems to instantly revert back to its normal state when the magnetic field is removed. Overall, I am happy with this purchase. An option to have this same paper in larger dimensions would be nice - as well as a lower price - but I am currently happy with my purchase.
Review: Diese Folie ist zwar deutlich teurer als die üblichen monochromatischen Magnetflux-Folien, ermöglicht aber tatsächlich eine wesentlich differenziertere und zuverlässig reproduzierbare Darstellung von Magnetfeldern. Außerdem weist diese Folie fast keine Remanenz auf und kann auch in stärkeren Magnetfeldern beliebig oft wiederverwendet werden.
