Magnetic strength difference between .4mm and .8mm thick magnetic sheets?
Yes, the magnetic strength is much greater using the .8mm thickness. I'm not sure how big a difference in strength but double is possible.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
