How to measure the pulling force of a magnet?

Magnets are very practical tools, and they are widely used in life and work. In some important occasions, we need to know the pulling force of magnets to determine their use effect and safety range. So, how to measure the pulling force of magnets?

First, we need to prepare some measuring tools. Common magnet pulling force measuring tools include magnetometers, hanging scales, pressure sensors, traction meters, etc. Among them, magnetometers are the most commonly used measuring tools, which can be used to measure the attraction and repulsion of magnets; while hanging scales, pressure sensors and traction meters are more suitable for measuring the pulling force of magnets.

Next, we need to choose a suitable measurement method. There are many ways to measure the pulling force of magnets. The following two are more commonly used methods:

The first method is to use a hanging scale or a pressure sensor. We can hang the magnet on a hanging scale or clamp it between pressure sensors, and then measure the gravity or pressure on the magnet to get the pulling force of the magnet.

The second method is to use a traction meter. We can fix the traction meter on a fixed point, and then connect the magnet to the other end of the traction meter, gradually increasing the size of the traction until the magnet leaves the traction meter. At this time, we can get the pulling force of the magnet.

Regardless of the measurement method, we need to pay attention to some details. For example, when using a crane scale or pressure sensor, we need to pay attention to the accuracy and maximum load-bearing capacity of the crane scale or pressure sensor; when using a traction meter, we need to pay attention to the uniformity of the pulling force and the smoothness of the pulley. Only by paying attention to these details can we measure the pulling force of the magnet as accurately as possible.
