I intend to use something like this fixed to a wall http://www.utcfssecurityproductspages.eu/HQ/products_single.php?cd=3&product=FE581 If it isn't enough (490 N), then I'll have to use a stronger one. How can I calculate the holding power I need? thank you

Hi What is the minimum kgf (or N) of a magnet to hold a 4m x 2.5m door? The door will be outdoor and wind can hit it. The function of the magnet is to keep it open. Best regards josh
