• Securely attaching all manner of fixtures to plate steel, or for a heavy gate. Consider the cheaper "pot" type especially if the steel is thinner.
• Retrieve or "fish" for lost steel items.
• Too strong? Glue 1 or 2 mm thickness of a non-magnetic material to the pole surface.
• For making "sweeper" magnets,i.e. magnet "brooms". (Google it.) Attach a row, countersink outermost, along one side of a thick (5mm or more), flat, steel bar, say 1 to 2 cm apart in order to project the field further from the magnets. Put the assembly inside a non-magnetic housing, say plastic down-pipe or S/S channeling.
