1. A manually propelled hand held portable high energy magnetizer device for magnetizing flexible magnetizable sheet material, the device comprising:
a housing having a bottom portion; and
a magnetizer disposed within the housing, the magnetizer comprising at least one magnetic roller configured to freely rotate within the housing and at least partially extend below the bottom portion of the housing in contact with an upper surface of the flexible magnetizable sheet material, the at least one magnetic roller is configured or arranged to multipole magnetize the flexible magnetizable sheet as it rotates in contact with the upper surface of the flexible magnetizable material, the magnet roller comprises one or more magnet stacks of circular magnets arranged with alternating polarity,
wherein the hand held portable high energy magnetizer device is configured to be positioned on top of the flexible magnetizable sheet material and then a user manually propels the portable high energy magnetizer device by pushing or pulling the hand held portable high energy magnetizer device along a length of the flexible magnetizable sheet material to rotate the at least one magnetic roller in contact with the upper surface of flexible magnetizable sheet material to magnetize same.
