How is “lifting power” measured?

There is no standard for measuring “lifting power” for magnetic sweepers. Some manufacturers use pounds of nails, some use pounds of a steel bar. All magnets will hold more pounds of a steel bar than pounds of nails because it’s difficult to arrange many nails closely onto the magnet.

However while manufacturers refer to “Lifting Power” it should really be called “Holding Power” because it refers only to the maximum weight that the magnet will “hold onto” nowhere does it mention the height that the magnet can pick this weight up from. This is why Bluestreak does not consider “Holding Power” as good of a performance indicator. We believe maximum “Lifting Power” is a better indicator.
