Where our magnet figures come from
No products on this site have been measured here yet. The comparisons use published specifications, and missing results are marked as not yet measured. This page explains how to read the information we have and what a product test would need to add.
Published figures and estimates
A listed thickness is a seller's figure. A listed pull force describes the test conditions supplied with that figure, often a magnet pulled straight away from a flat steel plate. It does not tell you how much weight the same magnet can hold without sliding down a fridge.
Paint, surface texture, contact area, and the direction of the load all affect the result. A working estimate can help compare materials, but it should not be treated as a measured rating for your door. The strength chart explains the distinction alongside the published figures.
What a physical test would record
A useful pull-force test would identify the magnet, its dimensions, the steel surface, the gauge, and the direction of the pull. Repeated readings would show how much the result varies. A separate test on a painted fridge surface would check sliding resistance under a hanging load.
Thickness would be checked with calipers at the center and both edges. Printed samples would be photographed with the same lighting and test image so readers could compare the results. A record of corner lift would need before and after photos taken over a stated period.
We would publish the sample details, method, and readings together. Until those records exist, the comparison tables remain comparisons of listed specifications.
Photos and illustrations
Original sample photographs would identify the product and the conditions shown. A picture alone cannot establish a pull-force measurement or a long-term wear result.
