Abstract
A magnetic wellbore cleaning tool having a plurality of magnetic ridges spaced longitudinally between top and bottom centralizers. In operation, the magnetic ridges modify the velocity of passing fluid circulating in the wellbore such that the fluid remains in close proximity to the tool's magnetic field thereby allowing for collection of ferromagnetic debris suspended in cleaning fluid circulating in a wellbore.
