The pull force of a magnet is a measure of the strength of the magnet's magnetic field and its ability to attract ferromagnetic materials. As the pull force is measured in laboratory conditions, most real world applications will not reach the maximum pull strength listed. There are several methods for measuring the pull force of a magnet, including:
Force Gauge: A force gauge, also known as a spring scale or spring balance, can be used to measure the pull force of a magnet by suspending the magnet from the scale and measuring the force required to pull the magnet away from a ferromagnetic surface.
Pull Tester: A pull tester is a specialized device that is used to measure the pull force of a magnet. It consists of a platform that holds the magnet and a load cell that measures the force required to pull the magnet away from the platform.
Digital Force Gauge: A digital force gauge is a precision instrument that uses a load cell to measure the pull force of a magnet. It typically has a digital display that shows the force in real-time and can be used to measure forces over a wide range of values.
Magnetic Field Meter: A magnetic field meter is a device that measures the strength of the magnetic field produced by a magnet. It can be used to measure the pull force of a magnet by measuring the strength of the field at a specific distance from the magnet.
The best method for measuring pull force depends on the specific requirements of the application and the precision and accuracy needed. Many factors can impact why the magnet may not be performing at the listed pull strength. Most commonly it is due to gravity. The strength of the magnet drops 65 percent or more when used in a horizontal/lateral application such as on the side of a refrigerator, rather than in a vertical application such as on the underside of a metal beam. Other factors such as the composition and thickness of the ferromagnetic materials being used will also impact performance.
These magnets are so strong that it is difficult to separate them without using some kind of prying tool, my fingers alone are too weak to do it. They will do the job I purchased them for very well.
The magnets I received were shipped quickly and securely, and I had no issues with delivery. They were packed well and in good shape when I received them. I noticed no defect with the magnets and I I was able to use them exactly as I intended on back of a piece of jatoba for a magnetic knife strip. I routed a track to 1/8” and glued and epoxied the magnets in place. The magnets provide sufficient pull strength to hold knives without being too energetic about grabbing them from the hand. These met my need precisely and I would purchase again if I decide to make more of these magnetic knife holders.
I used the magnets on a wooden toy box for my grandson. Easy to install and the perfect strength. I will be buying different sizes for other projects.
Ordered these magnets for a project that I was working on. Received as stated & described, the magnets are what I was looking for. Will order from them again.
Used this for a hobby project I’m working on and the magnets held my project together very well. The finish on them were uniform and packaged them very well. They were shipped and received very timely and will be re-ordering more.
Good customer service, great price & quick to ship
I was hoping to find a strong, low profile magnet to use on my project - which is a restoration of a WWII Army Footlocker. I wanted to attach some old photos and postcards to the underside of the lid, but without using any permanent adhesives which may have affected my paint job. These worked perfectly!
Just what I needed and at the right price.....
Will purchase more when needed.
Have used before & reordered magnets for customized windows alarm contacts. Work fantastic & slim profile allowing no issues opening & closing windows.
me use these to stop 1/24 scale drag racing slot cars !!
1/2 x 1/8 Inch Strong Neodymium Rare Earth Disc Magnets N52 (24 Pack)
Magnetic knife board, that worked perfectly.
