How to keep neodymium magnets from breaking?

Neodymium magnets are powerful and versatile, making them popular for various applications. However, they can be prone to breaking due to their brittle nature and susceptibility to certain environmental factors. In this article, we’ll explore the properties of neodymium magnets, factors that can cause them to break, and tips for preventing breakage and maintaining longevity.

Factors That Can Cause Neodymium Magnets to Break

Mechanical Stress

One of the primary reasons neodymium magnets break is due to mechanical stress. If you drop, snap, or apply too much force to the magnets, they may chip or shatter. These strong magnets, even if small, possess a powerful attraction and can collide with each other or other objects if not properly controlled.

Thermal Stress

Encounters with elevated thermal conditions risk the demagnetization of neodymium magnets, precipitating their fracture. It is paramount to ensure these magnetic entities remain distant from heat-emitting bodies and nestle them in a frigid, arid place.


Exposure to moisture, chemicals, or acidic environments may cause corrosion in neodymium magnets. This corrosion weakens the magnet and ultimately results in breakage. Keeping the magnets in a clean, dry environment and avoiding exposure to chemicals is crucial to prevent corrosion.

As neodymium magnets are incredibly strong yet exhibit brittleness, adhere to several crucial measures to preserve their integrity: Apply adhesives for affixing the magnet to surfaces, employ apt handling methods like donning gloves and utilizing both hands during interactions, and securely store them safely away from other metallic objects.

Use Appropriate Adhesives

If you need to attach a neodymium magnet to another object, use an appropriate adhesive designed for use with magnets. This will help ensure a strong bond and minimize the risk of the magnet breaking due to stress or impact.

Proper Handling Techniques

To prevent mechanical stress, it’s essential to handle neodymium magnets with care. Always wear gloves and use both hands when handling large or powerful magnets. Keep magnets separated from each other and from other ferromagnetic materials to prevent sudden impacts.

Proper storage is crucial to prevent neodymium magnets from breaking. Store them in a cool, dry place away from heat sources and moisture. If possible, keep magnets individually wrapped or separated by spacers to avoid them sticking together or colliding. Keep them away from electronics, as their strong magnetic field can damage sensitive components.

Appropriate Usage

Using neodymium magnets for their intended purpose and within their specified limits can help prevent breakage. Avoid subjecting magnets to excessive force or stress, and do not use them in high-temperature or corrosive environments unless specifically designed for such conditions.

How to Handle Neodymium Magnets Safely

Wear Protective Gear

When handling neodymium magnets, it is essential to wear protective gear like gloves and safety goggles to protect your hands and eyes from potential injuries caused by sudden impacts or broken magnet fragments.

Use Spacers

Spacers made from wood, plastic, or foam can prevent the magnets from colliding and potentially breaking when working with multiple neodymium magnets.

Keep Magnets Separated

Store neodymium magnets separately, ensuring that they are not in direct contact with one another. This will help prevent accidental collisions and breakage.

Maintenance Tips for Neodymium Magnets

Cleaning Neodymium Magnets

Keeping your neodymium-magneter clean can help prevent corrosion and maintain their performance. Clean them with a soft cloth, sponge, and mild soap, then rinse and dry thoroughly. Avoid using abrasive cleaners or scrubbers that could damage the magnet’s surface.

Inspecting Magnets for Damage

Regularly inspect your neodymium magnets for signs of damage, such as chips, cracks, or corrosion. If you notice any issues, replace the magnet to prevent further damage and potential breakage.


Neodymium magnets are incredibly powerful and useful in many applications, but their brittle nature makes them prone to breaking if not handled and maintained properly. Grasping the elements contributing to neodymium magnets’ deterioration allows for applying apt handling methods, secure storage, suitable usage, and routine maintenance, thereby prolonging their longevity and maximizing the utility of these adaptable magnetic wonders.

Ofte stillede spørgsmål

Why are neodymium magnets prone to breaking?

The brittle composition of neodymium magnets makes them prone to chipping, cracking, or shattering under mechanical stress, thermal stress, or corrosion.

How can I prevent my neodymium magnets from breaking?

Treat them gently, securely stow them in a chilly, moisture-free location, employ them for their designed objective, and consistently maintain them through cleansing and examination for potential harm.

Can I use neodymium magnets in high-temperature environments?

Refrain from utilizing neodymium magnets in high-temperature environments, unless explicitly crafted for such applications, since they risk losing their magnetism and becoming increasingly susceptible to breakage.

How should I clean my neodymium magnets?

Use gentle fabric, sponge, and mild soap to cleanse your magnets, followed by thorough rinsing and drying. Eschew abrasive cleaning agents or scrubbers that might harm the magnet’s exterior.

What should I do if I notice damage to my neodymium magnet?

Upon detecting indications of impairment, including chips, cracks, or corrosion, opt for magnet replacement to avert additional degradation and the possibility of breakage.
