Neodymium Magnets: What Are They Used For?

The introduction of modern technologies has made magnets extremely versatile and usable in different industries. Whether it be the medical, entertainment, business, or energy sector, magnets serve multiple purposes that make them one of the most diverse tools.

Without realising it, you have likely encountered them in different aspects of your daily life–a testament to how prevalent and useful they are.

Among the different kinds of magnets that exist today, neodymium magnets are said to be the strongest types of magnets available in the market. Though they may sound unfamiliar or foreign, you will be surprised to know that you have most likely already seen these magnets or used them.

Neodymium magnets are used for several applications in multiple industries, making them one of the most widely-used earth magnets in the present day. They are particularly common among modern products since they can deliver strength without being too heavy.

If you’re curious to know where neodymium magnets are used or how you have encountered them, here are some of the most common applications of these magnets.

Magnetic Resonance Imaging (MRI) Tests

If you’re well-acquainted with the medical industry, then you would be familiar with MRI scans. These tests use radio waves to get an image of your organs and tissues to detect possible abnormalities or health concerns. MRI scans work by creating a strong magnetic field that aligns the protons in one’s body. Given the nature of the procedure, strong magnets are needed to achieve the purpose of MRI testing and capture accurate images.

Audio Equipment

Your speakers, headphones, and microphones contain coils that allow electric currents to flow, as well as a permanent magnet that generates a strong magnetic field. As current flows through, the coil becomes charged and interacts with the permanent magnet in a series of attraction and repulsion. The alternating movement creates variations in the pressure of the surrounding air, effectively forming sound waves–the music and sounds that you hear.


Though it may sound unusual, magnets are also frequently used in the jewellery industry. Neodymium magnets are particularly common in jewellery clasps since they can provide a good hold and lock to secure your jewellery pieces. Another advantage is that jewellers can use this type of magnet and achieve its benefits–particularly its strength and permanence–without having to use too much.

Try to look for a bracelet or necklace and observe its clasp. Given its size, it almost seems impossible to think of how a magnet can fit in it, but with a neodymium magnet, such is possible.


Given the versatility of magnets for medical uses, it is no surprise that neodymium magnets have also made their way to the dentistry field. Modern dentures make use of magnets that help keep the device in a stable position thanks to their strong magnetic force.

They are highly recommended for patients who are not candidates for implants since they function similarly but do not require as much gum or jawbone as them.

Home Projects

Neodymium projects are equally popular among homeowners who regularly engage in projects, such as organising your garage tools, hanging picture frames, or making door catches. You may not notice it, but there are tons of magnets found in your home alone.

Whether it be your cabinet doors or office supplies, magnets can be found in virtually anything, which means you can also repurpose them for other things.
