Neodymium cube magnets Description

Neodymium cube magnets are small, powerful magnets made from a rare earth metal called neodymium. They are typically small in size, ranging from a few millimeters to a few centimeters in length, width, and height, and are often square or rectangular.

Neodymium cube magnets are particularly useful for creating 3D magnetic structures or as building blocks for larger magnetic assemblies. They can be stacked and arranged in different configurations to create custom shapes and structures, and their strong magnetic force allows them to securely hold objects in place.

Neodymium cube magnets Characteristics

Neodymium cube magnets Applications

Handling and Safety

Handling neodymium cube magnets requires caution due to their strong magnetic pull, which can cause them to snap together unexpectedly. This can result in injuries or damage to the magnets themselves. Additionally, small magnets pose a choking hazard and should be kept away from children and pets. When working with these magnets, it's also important to consider their potential to interfere with electronic devices and magnetic storage media.


What are neodymium cube magnets?
Neodymium cube magnets are strong permanent magnets made from an alloy of neodymium, iron, and boron, formed into a cube shape. They belong to the rare-earth magnet family and are known for their exceptional magnetic strength relative to their size.
How strong are neodymium cube magnets?
The strength of neodymium cube magnets varies depending on their size and grade, but they are among the strongest magnets available per unit volume. Their magnetic field can be significantly powerful, allowing them to hold many times their own weight.
What are the common uses for neodymium cube magnets?
Neodymium cube magnets are used in a wide range of applications, including in educational settings, for hobby and DIY projects, for holding and mounting objects in both industrial and consumer products, and in certain health and wellness products like magnetic therapy devices.
Can neodymium cube magnets be used outdoors?
Neodymium cube magnets can be used outdoors but require a protective coating to prevent corrosion. Common coatings include nickel, epoxy, and gold, which protect the magnet from moisture and environmental elements.
How do you handle neodymium cube magnets safely?
To handle neodymium cube magnets safely, always keep them away from electronic devices and magnetic storage media. Use protective gloves to avoid pinching fingers between magnets, and never allow children or pets to play with small magnets due to the risk of ingestion and the serious health hazards that can follow.
Do neodymium cube magnets lose their magnetism over time?
Under normal conditions and temperatures, neodymium cube magnets retain their magnetism for decades. However, they can lose their magnetism if heated above their Curie temperature, exposed to a strong demagnetizing magnetic field, or if their protective coating is breached and corrosion sets in.
Can neodymium cube magnets damage electronic devices?
Yes, the strong magnetic fields of neodymium cube magnets can damage electronic devices and magnetic storage media like hard drives and credit cards. It's important to keep magnets at a safe distance from such devices.
How can I separate two stuck neodymium cube magnets?
Separating two stuck neodymium cube magnets can be challenging due to their strong attraction. Slide them apart rather than trying to pull them directly apart, and consider using a non-metallic wedge or spacer to help push them apart safely.
Are there different grades of neodymium cube magnets?
Yes, neodymium cube magnets come in various grades, which indicate the strength of the magnet. Higher grades (indicated by higher numbers and sometimes letters for temperature rating) are stronger but may also be more brittle or require more precise handling.
Can neodymium cube magnets be customized?
Neodymium cube magnets can be customized in terms of size, grade, and coating to meet specific needs. Customization might be necessary for specific industrial applications or unique design requirements.
