The King of Pin magnet, aka. “King Pin” is a strong neodymium magnet encased in a 20mm diameter steel pin casing that stands at 25mm tall.
This shiny King Pin magnet is not just about looking tough, it can hold up to 70 times it’s own weight side ways (Shear force)!
(If you try pulling it directly, the pull force will be at least twice the shear force)
Below photo shows 2 pcs of King Pin magnets attached to a regular metal store room door (Aka common bomb shelter door in BTO flats), one of it has a 2kg pack of sugar hanging from it, another has 2 cartons of 1 liter milk making the approximately 2kg load.
Warning : If you are trying this at home make sure to gradually increase the weight starting from 1.5kg as different thickness of the metal and surface conditions will have varying results.
We will not be held responsible for spilled milk 😉 …
Another feat of this King Pin… single handedly holding 35 sheets of A4 size (80gsm) papers against a thick metal wall (photo below), this King Pin is strong and tough thanks to it’s elegant looking steel case, yet a joy to handle. Unlike plain neodymium magnet that is this powerful, the tendency to break when drop or subjected to strong impact due to brittle nature of neodymium magnet is a concern.
The pin steel case serves 3 purposes… It makes the magnet much more durable, increases the magnetic strength of the magnet base and provide a comfortable grip when you need to detach this magnet.
