Magnetic sweepers consist of parts like lumber, plastic wheels, bolts to act as the axle of the wheel, washers for wheel spacing, broom handle, aluminum cover, a sheet steel backing, and neodymium magnets. There is also an additional cover for the magnets which shield the magnets from damage and also creates a way to remove the attracted materials easily and we don't need to pick up the rusted materials from the sweeper one by one.
