Neodymium Magnet Safety and How to Handle Neodymium Magnets

Magnets are hazardous objects. And while they may appear small and harmless, they can cause detrimental effects on those handling them. So, from understanding their properties to implementing proper storage and handling techniques, this guide provides an essential resource for individuals using neodymium magnets in various contexts, be it in everyday items or more specialised applications. Find out more below.

Why is magnet safety important?

Magnet safety is a fundamental consideration due to the pervasive presence of magnets in our daily lives, ranging from household items to advanced technological applications. However, their significance lies in understanding the potential risks associated with magnetic fields and adopting strict practices to prevent mishaps.

Magnets possess considerable force, which requires cautious handling to prevent accidents and injuries. This is particularly crucial in medical settings, where powerful magnets are integral to technologies like Magnetic Resonance Imaging (MRI), demanding strict adherence to safety protocols for the wellbeing of patients and healthcare professionals.

Similarly, in school settings where magnets may be used for experimental purposes, knowing the dangers of these objects means everyone can learn in a safe environment.

While these are just a couple of examples, it is paramount to be aware of the established guidelines regarding magnet strength, storage, and handling.

Neodymium Magnet Safety Concerns

Neodymium magnet safety concerns are rooted in their potent characteristics. From magnetic interference to flammability and jumping, understanding the risks is crucial for safely handling and applying neodymium magnets. Below, we look at the main dangers of these small but extremely powerful objects.

Magnetic Interference

Neodymium contains an incredibly powerful magnetic field, so it can be a significant risk if it comes into close contact with particular objects. More specifically, neodymium magnets can disrupt various electronic equipment, leading to various hazardous repercussions. So, when storing neodymium magnets, you must keep them away from hard drives, disks, and videotapes, as their magnetic influence can adversely impact electronic storage devices.

In addition, you should also be very cautious when handling these magnets around individuals with pacemakers or other implanted devices, as the powerful magnetic field may interfere, potentially causing severe health and safety effects.


The brittle nature of neodymium magnets also comes with a substantial risk of breakage, particularly when quickly drawn together. The force generated during this magnetic interaction has the potential to chip or shatter the magnets, creating flying shards and fragments that cause imminent dangers to both handlers and those around them.

To mitigate these risks, handling these magnets with care is essential, avoiding rapid and forceful interactions. You should also always take protective measures, such as wearing safety gear when handling these powerful objects.


The strong, attractive force of neodymium magnets, even from several inches away, comes with a considerable risk to humans. Depending on the magnet’s size, this force is potent enough to cause skin pinching and bodily injury, potentially resulting in broken fingers.

Accidental ingestion is also another risk, as these magnets can attract across the membranes of the intestines and other organs, leading to severe damage and, in extreme cases, fatal consequences.


The flammability of magnets, particularly neodymium magnets, comes from the potential combustibility of their dust or powder. When neodymium magnets are mechanically damaged, such as through drilling or grinding in poorly ventilated areas, it poses a significant fire hazard. The resulting dust, made of fine particles with reactive properties, has the potential to combust efficiently under the right conditions.

Therefore, it is crucial to exercise caution when working with neodymium magnets and to avoid activities that may generate dust in environments lacking proper ventilation.

How to store neodymium magnets correctly

Magnet safety is not just about preventing accidents; it is also about preserving the longevity and effectiveness of these powerful magnetic objects. As such, you must store your magnets away safely. Some ways in which you can do this include:

  • Keep away from sensitive devices: Neodymium magnets can interfere with electronic devices, so store them away from hard drives, disks and electronic equipment. Maintaining a safe distance helps prevent unintended disruptions to the functioning of these devices.
  • Use non-magnetic spacers: When storing multiple neodymium magnets, use non-magnetic spacers made of plastic, wood or cardboard. These spacers act as a buffer, preventing magnets from unintentionally attracting each other. This reduces the risk of accidents during storage and transportation.
  • Store in a cool, dry place: Neodymium magnets are susceptible to corrosion, particularly in humid conditions. To prevent corrosion and maintain their optimal performance, store them in a cool, dry place. You should also avoid exposing the magnets to extreme temperatures to maintain their integrity.

How to handle neodymium magnets safely

Despite the dangers of magnets, there are several ways to reduce the risk of accidents. Some of the most important steps you should take include:

  • Wear gloves: Given the risk of pinching and sharp edges, wearing gloves when handling neodymium magnets is an essential precaution. Gloves provide a protective barrier, reducing the likelihood of injuries, mainly when working with multiple magnets or handling broken pieces.
  • Exercise caution: When dealing with strong neodymium magnets that attract forcefully, you should exercise caution when separating them. Sudden movements can lead to unexpected jumping or snapping together, posing risks of pinching or crushing. Use a deliberate and controlled approach when handling magnets to avoid accidents.
  • Keep away from children: Neodymium magnets cause a significant risk if ingested, particularly by children. Due to their small size and attractive nature, there is a risk of accidental ingestion. In addition, you should continually educate children about the potential dangers of handling these magnets and ensure they are stored in a location inaccessible to young children.
