(143 g) Pull Force, Case 1: 77.34 lbs Pull Force, Case 2: 203.5 lbs Max Operating Temp: 176ºF (80ºC) Brmax: 13,200 Gauss BHmax: 42 MGOe These sturdy rings are quite useful.  They are very strong and can easily be bolted to a wall for hanging heavy objects or holding tools in place.  They are great for dragging on the ground or in water to retrieve lost objects.  These rings are strong enough to repel each other with enough force to support the weight of one magnet at a height of over 4 1/2" as seen in the bottom picture on the left. Pull Force, Case 1 vs. distance: Magnet to a Steel Plate. Pull Force, Case 2 vs. distance: Between 2 Steel Plates. Pull Force, Case 3 vs. distance: Magnet to Magnet. Pull Force, Case 4 vs. distance: Magnet to Magnet Repulsion. Click here for a depiction of the magnetic field. View B-H curves for this magnet. Click here to download a PDF Specification Sheet.
