What is a Pull Force Test?
A pull force test is a scientific measure of how much force is needed to remove a magnet from a surface like Neodymium magnets. The test is typically used to measure the strength of magnets.
The most common way to do a pull force test is to use a weight or string attached to a magnet and measure the amount of force needed to remove the magnet. You can also use a spring scale or an electronic motor torque meter to measure the rotational force.

How to Perform a Pull Force Test
Pull force testing is an important step in the manufacturing process of magnets such as Bonded NdFeB magnets. It is used to determine the strength and durability of a magnet. The test can be performed with either a static or a dynamic test. Static tests will measure the pull force while the magnet is stationary. Dynamic tests will measure the pull force while the magnet is in motion.
There are several factors that can affect the results of a pull force test. These include the size of the magnet, the type of material it is attached to, and the amount of torque applied. To ensure accurate results, it is important to follow specific guidelines when performing a pull force test.
Results of a Pull Force Test
In order to test the strength of different types of magnets such as Sintered NdFeB magnets, we performed a pull force test. We used a calibrated weight to measure the amount of force needed to remove the magnet from the metal surface. The results are shown in the table below.
Magnet Diameter (mm) Pull Force (N)
0.8 11
0.6 16
0.4 25
0.2 36
Conclusion
If you are in the market for a pot magnet to use in your next industrial or scientific application, you will likely need to perform a pull force test to determine the appropriate diameters. This guide will walk you through the process of performing a pull force test and provide some tips on how to choose the correct diameter for your application.
