Why is this true? We suspect two factors are involved: steel thickness and paint thickness. They measured much stronger on the filing cabinet! The little hooks, however, were quite the opposite. Magnets are weird sometimes.įor example, the MMS-E Mounting Magnets and the big hooks were all slightly stronger on the door, compared to the filing cabinet. It’s not always obvious before you test it out. What holds true in one situation might not for another.
Unfortunately, the more we test magnets the more we keep discovering how the answers often depend on the situation. We hope our experience can help folks order the right magnets for the job. The whole reason we test all these magnets is to find some no-nonsense, straight answers to share. We gathered these magnets and a few others to test them on a few common surfaces. The closer the hook is to the wall, the less likely it is to rotate away from the wall.
This helps reduce the leverage of a load trying to pry the magnet off. Notice how the hook curves very close to the wall you’re sticking the magnet to. With the whole thing covered in a grippy, rubber-like coating, they are great at providing that extra friction.Īnother subtle feature is the hook itself.
These hooks have an internal disc of steel, on which an array of disc magnets are arranged. There are a lot of really smart magnetic design choices embedded inside. From the outside, this magnetic assembly is a stout plastic disc, with a rotating hook for hanging things on.
