Permanent magnet lifter
Permanent magnet lifter
(OP)
Will someone please explain how the permanent magnet lifter works. I am particularly interested in how it is possible to turn on and off the the attraction that this lifter has on the material being lifted.





RE: Permanent magnet lifter
There is usually a small amount of attraction from the iron when the device is off, because of residual magnetism. Usually this is not noticable.
RE: Permanent magnet lifter
Magnet feet for measuring dials work on same principle.
