Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the ability to customize to complex applications,
- Huge importance in electronics industry – they are commonly used in data components, electric drive systems, advanced medical instruments, and modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a base made of low-carbon steel, functioning as a circuit closing element
- with a thickness of at least 10 mm
- characterized by even structure
- with direct contact (without impurities)
- during pulling in a direction vertical to the plane
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Protect data
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
This is not a toy
Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Do not overheat magnets
Avoid heat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Immense force
Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and respect their power.
Do not drill into magnets
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Implant safety
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Pinching danger
Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Precision electronics
A strong magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to prevent damaging the sensors.
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
