Magnet Calculator – Calculate Pull Force of Magnets

Use the magnet calculator to calculate the strength of a magnet. You enter the size of the magnet and the distance between the magnet and a metal surface. The magnet calculator then calculates how much force the magnet exerts on the metal at the given distance. If we have magnets with a strength close to the one you have calculated, we list them below.
Be aware that the magnet calculator is not 100% accurate, but it gives a pretty good indication of the strength a magnet has at various distances from a metal surface.
