Which magnets are stronger permanent magnets?

Neodymium permanent magnets are currently the stronger permanent magnets that are commercially accessible, and as a result, they find employment in a wide number of applications. In this article, we will talk about neodymium permanent magnets and the various applications they have. Let's start.

What are permanent magnets? 

Permanent magnets are materials that retain their magnetic properties over an extended period of time, thus the name. These components can be found in a wide variety of products, including refrigerators, toys, and even tools. Objects that are built from specific materials can generate their consistent magnetic field if they are constructed to be permanent magnets. The arrangement of the electrons within the material's atoms is what generates the magnetic field created by the substance. 

Permanent magnets are made from substances that already include an inbuilt magnetic field inside their composition. These substances are used in the construction of permanent magnets. The principal kinds of permanent magnets are neodymium magnets, ferrite magnets, AlNiCo magnets, SmCo magnets, and rubber magnets.

Which is the stronger permanent magnet? 

Neodymium magnets are the stronger permanent magnets. Due to the fact that they contain one or more of the rare earth elements listed on the periodic table, neodymium magnets are a form of permanent magnet that is also known as rare earth magnets. These are examples of permanent magnets, each of which possesses a magnetic force that is up to one billion times stronger than the tensile strength of steel.

Neodymium magnets are ten times stronger. They weigh only a few grams each while being the most powerful magnets ever made for commercial use and they hold this distinction. The tetragonal structure of the NdFeB magnet results from the combination of neodymium, iron, and boron (Nd2Fe14B). Magnets made from neodymium have exceptionally strong heat resistance; in fact, they can sustain temperatures that are higher than 200 degrees Celsius.

Which Is The Best Procedure To Make A Permanent Magnet?

How are neodymium permanent magnets made?

The production of neodymium-iron-boron (NdFeB) magnets is a difficult and complex process that involves a significant amount of time and effort. To produce it, iron, neodymium, and boron are subjected to extremely intense crushing before being melted in a vacuum. After that, they are melted in an airless environment. During the process, the three components are magnetized and compressed to the point where they form a straightforward structure, which is typically in the form of a cylinder or cube. As soon as it reaches this point, it must be heated in a vacuum so that it can gradually cool off over time.

The alloy will start to develop a more crystalline structure from this point forward, which will make the upcoming magnetization process easier. At this phase, the sizes that have been specified begin to take shape. After that, a coating made of copper and nickel is applied to the raw magnet. This coating serves two purposes: it protects the magnet from readily oxidizing and it provides the magnet with an unmatched appearance.

When we have reached this point, the magnets will need to be magnetized by passing through a large magnetic field produced by a magnetic coil. This will align the molecules and crystals in the magnetic field produced by the coil. Once we have reached this point, the magnets will need to be placed in a magnetic coil through which a current will pass. Your neodymium magnets are now prepared for use.

Applications of neodymium magnets:

Since neodymium magnets are the stronger permanent magnets, they are used in a wide variety of applications. Let’s discuss a few.  

  • They are a component of the generators that are found in wind turbines. The reason for this is that the production of electricity relies on neodymium magnets.
  • When it comes to powering their DC motors, hybrid and electric vehicles frequently use powerful neodymium magnets.
  • Neodymium magnets are found in the most cutting-edge audio headphones and speakers, and these magnets are responsible for the enhanced sound quality as well as the entire spectrum of bass.
  • Neodymium magnets are utilized in a significant amount of today's medical equipment. For instance, these magnets are a crucial component of MRI scanners, which allow for an interior view of the human body to be obtained without the use of radiation.
  • Typical neodymium magnetic separators are used in the operations of recycling and garbage removal. These processes involve sorting materials into different categories.
  • The magnetic holding relay, the watt-hour meter, the water meter, the microphone, the reed tube, the sensor, and so on are all examples of other applications.
