Pull Force Required to Pull Q Magnet Models from Metal Plate
The pull force of a magnet is the amount of perpendicular force needed to remove it from an object it is magnetically attracted to. In this case we used an industrial force guage and a large piece of iron around 25mm or 1" thick so it would not become magnetically saturated - see the image below for a demonstration.
The magnetic pull force is a measure of how strong its magnetic field is and the properties of what it is attached to.
The following table provides the pull forces for each of the Q magnet models.
Units are Newton (N), Kilogram Force (kgf), Pound Force (lbf).
