Neodymium Arc Magnets VS Neodymium Bar Magnets

Neodymium magnets can be used in a variety of applications. This is because they come in many different shapes. Neodymium arc magnets and neodymium bar magnets are good examples of commonly sold shapes. They have several uses in varied industries. What are the differences between them? In this article, we will take a close look at the differences between the neodymium arc magnets and neodymium bar magnets.

Neodymium Bar Magnets

Bar magnets are magnetic materials made into bar shapes. The bars have two unlike poles, the South Pole and the North Pole. The poles have equal magnetic strength. Neodymium bar magnets are permanent magnets that have many desirable qualities. Neodymium bar magnets are used in applications that require high magnetic capacity per weight. Some of these applications include computer hard disk designs, electricity generators, and hybrid/electric automobiles. One kilogram or 2.2 pounds of neodymium is required for one Toyota Prius. The first purely electrical model aircraft was made using this type of magnet within the first decade of the 21st century. These may soon replace the internal combustion models. At all costs, keep them away from young children or even your pets. Small neodymium bar magnets pose a serious choking hazard. They should never be swallowed or inserted into any body part. The magnets can easily stick together across your intestines. This can result in serious health hazards or even death. neodymium bar arc magnet

Neodymium Arc Magnets

An arc is just a small segment of a professionally produced NdFeB magnet. It can be customized to match the customer's specifications. So it is wise to purchase an arc segment after determining the correct size for a particular project. To shop quickly and conveniently, a customer can shop online. Numerous stores target USA customers. So make sure you pick a reputable and licensed seller of a variety of magnets. A neodymium arc magnet is made via a complex technique that entails grinding and wire cutting. It is, therefore, necessary to look for the following characteristics before ordering arc segments:

  1. Outer radius/diameter
  2. Inner radius/diameter
  3. Circumference of the round edge
  4. Thickness
  5. Length
  6. Angle

It is essential to note that arc magnets made from Neodymium, Iron, and Boron are not unique to other magnet shapes. All of them have similar properties about factors such as coercivity, Curie temperature, resistance to corrosion, and energy product. However, it is vital to note that neodymium arc magnets can be weaker or stronger depending on the N-rating or grade. For instance, an arc-rated N38 is automatically weaker than an arc-rated N55. A customer should be aware of the neodymium N-rating scale, which begins from N35 to N55. This will help them order neodymium arc segments that can assist them in finishing their projects.


Thank you for reading our article, hoping it can help you have a better understanding of the differences between the Neodymium Arc Magnets and the Neodymium Bar Magnets. If you want to know more about them, you can visit Stanford Magnets for more information. Stanford Magnets has been involved in R&D, manufacturing, and sales of permanent magnets since the 1990s, and provides customers with high-quality rare earth permanent magnetic products such as neodymium magnets, and other non-rare earth permanent magnets at a very competitive price.
