Automated Scientific Teaching Magnetic Field Detector Review

, I love playing with magnets and making fun games and gadgets with them. I've used green magnetic tape before but never found it that useful. This film, on the other hand, provides significantly more information about magnetic fields and gradients on a visually appealing color display. I feel like this will help shorten the trial and error cycle I go through when coming up with new ideas. Highly recommended for amateurs and teachers. I am sure that even professionals can benefit from it!

As advertised, these viewers (compared to others I've looked at) offer a slightly easier interpretation of analog field strength readings with really sharp gradients. Seems to have no memory/residual charge so degaussing doesn't seem necessary. They are mounted on some sort of sturdy cardboard with a 3/4 inch bezel all around to prevent the viewer from presumably coming into direct contact with the magnets being viewed. to protect the active bottom from damage, and it definitely looks like…

This product has a protective frame which is better than other products without a frame. The frame material isn't exactly stiff and is a little warped so the entire build isn't completely flat, but that's enough for most uses. I just wish the frame was hard plastic, not two sheets of rigid foam. I would be willing to pay extra for it. Second, this product has a full color spectrum display that allows you to see the strength of the magnetic field in color instead of monochrome, which is really…
