About Neodymium Magnets

Neodymium magnets are a type of rare earth magnet, often called permanent magnets, and are considered the strongest magnets in the world. They are up to 10 times stronger than all other ferrite, ceramic, or alnico magnets of equal size. Neodymium magnets are made by combining neodymium, iron, and boron to create an alloy that is then processed and shaped into the desired size. The resulting magnet is very strong for its size and is often used in applications where a strong magnetic field is needed in a small space. Neodymium magnets are brittle and can be easily damaged. They are also...

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....

All of our neodymium magnets are organized by shape and listed from the smallest to the largest available. Standard magnet shapes include discs, rings, cylinders, blocks, bars, cubes, and spheres. Some magnets are also available with countersunk holes or adhesive attached.Each magnet also has a corresponding strength or pull force rating measured in pounds or milligrams. The larger the magnet, the stronger the pull force generally speaking. Anything above seven pounds of pull force can pinch your fingers and should be handled carefully.

The surface field refers to the invisible force coming from a magnet. It is a force that completely surrounds the magnet and exerts a powerful push or pull energy when exposed to other magnetic materials. It is this field or force that makes magnets attract or repel one another, and the amount of this force determines exactly how strong the magnet’s attraction or repelling power really is.To measure the surface field strength of a magnet, scientists use something similar to a thermometer type of device called a Gauss Meter, where a higher value represents a stronger, more intense magnetic field.A...

There are many steps involved in the manufacturing process for neodymium rare earth magnets, also known as NdFeB magnets. Here is a high level overview of the main steps involved: Raw Material Preparation: The first step in the manufacturing process is to prepare the raw materials that will be used to make the magnets. This involves mixing the neodymium, iron, and boron powders together in the correct proportions to create the magnetic alloy. Compaction: The next step is to compact the magnetic alloy into a solid form. This can be done using a variety of methods, such as cold pressing, hot...
