1. A continuous discharge ceramic powered magnetic sweeper apparatus, configured for sweeping of metallic debris, the apparatus comprising:
at least one handle;
a frame connected to the handle;
at least one support wheel;
a frontal debris bin;
a plurality of drive wheels; and
a finned tube housing located between the drive wheels, the finned tube housing further comprising:
two or more ceramic magnet blocks forming a magnetic assembly;
a sealed non-magnetic finned tube; and
one or more rotating non-magnetic fins;
wherein the magnet blocks are continuously cleaned off as the magnetic sweeper apparatus is pushed forwards in the direction of operation;
wherein magnetic debris accumulates on the magnet assembly and is deposited in the frontal debris bin;
wherein the apparatus design utilizes magnetic field differences created by the magnet position and angle to achieve the automatic pick-up and drop-off of debris at different locations of the magnet assembly;
wherein the two or more ceramic magnet blocks in the magnet assembly are stacked to create a larger magnetic field;
wherein the ceramic magnet blocks are magnetized in alternating directions, alternating between south and north, creating stronger points in the magnetic field along the magnet assembly;
wherein the magnetic assembly is located between the drive wheels.
