How much it will hold depends on the friction between the surfaces, the shape of what is being held up, and a few other factors. Stuck to a vertical surface like a wall, a mounting magnet won’t necessarily hold up a weight that’s equal to the listed pull force number. Note: When loading the magnets in a different orientation, expect different results. Strengths range from just a few pounds, as with the tiny MM-C-10, to several hundred pounds from big 3” diameter magnets like the MMS-A-Z0. This is the force required to pull one of these magnets straight away from a steel surface. There are also a number of Rectangular Mounting Magnets available, with countersunk holes.Įach of our Mounting Magnets product pages includes a listed Pull Force number, expressed in pounds. Styles include:įemale threaded stud with steel hook, MM-E and MMS-Eįemale threaded stud with eye-hook, MMS-G only Mounting Magnets are available in both metric and standard/American/Unified sizes, millimeters or inches. By providing threads in a steel part, you get a sturdy mounting solution not possible with plain magnets. It is like trying to make usable threads in ceramic. We've tried in the past, but the threads shear as soon as torque is applied on a screw or bolt. Neodymium magnet material is so hard and brittle that you can’t make usable threads with it. This includes a number of options that include threaded steel features (with male or female threads) that you can attach using standard hardware. Our Mounting Magnets come in a variety of mounting options. Also, you get a lot of strength by having those poles close to one another, which provides a strong magnetic flux in the steel surface it sticks to.ģ. You could say that the Mounting Magnet is stronger because the magnetized steel makes the assembly act like a bigger magnet.
STRONG MAGNET FULL
In the magnetic field picture, the steel cup looks purple on the color scale because the steel is magnetically saturated - as full of magnetic flux as it can get. A Mounting Magnet gets a lot of its strength by the steel cup attracting to the surface, because the steel cup is magnetized by the magnet. With the steel cup of a mounting magnet, the steel structure redirects the magnetic field from the back-side of the magnet, turning it into more useful holding strength. You get a strong attraction where the magnet touches the steel, but the magnetic field on the opposite side of the magnet isn't doing much to provide pull force. With a plain disc magnet sticking to a steel surface, the magnetic field looks as shown in the top part of the magnetic field picture at left. Why is it stronger? Their construction consists of a disc or ring magnet sitting inside a steel cup. In terms of dollars spent per pound of pull force, they can be a better value than a plain magnet. If you took the magnet out of a Mounting Magnet, you might only see half the pull force that you had fully assembled.
A Mounting Magnet offers much more strength than you get with the magnet alone. Magnetic field of a disc magnet compared to a Mounting Magnet.
