Selecting Between Deep Field Passive Shunting And Shallow Field Active Shunting Lifting Magnets
Lifting magnets will achieve different hold forces depending on the thickness of the steel it is in contact with. Some magnets are geared towards lifting thin material (Active shunting) and some thicker material (Passive Shunting). Let's look at how the two compare at the midrange thicknesses we commonly handle in...
Passive shunting Magnets achieve their full hold force between 30mm - 80mm thick while most Active Shunting Magnets are achieving their full hold force between 9mm and 20mm. This is the range of thicknesses that are most commonly handled. What that means is that at some thicknesses of an enormous...
Ever heard of Residual Magnetism? What is it, and how does it affect your Lifting Magnets? Residual Magnetism occurs when a magnet fails to turn completely off. The magnetic flux is a result of a circuit being created between the rare earth magnets inside and the steel body of the magnet. The...
