Advantages and disadvantages of neodymium magnets.
Pros
- They retain magnetic properties for almost ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by external magnetic fields,
- By using a lustrous layer of nickel, the element gains an proper look,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in shaping and the capacity to customize to individual projects,
- Significant place in modern industrial fields – they are commonly used in computer drives, drive modules, advanced medical instruments, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of creating threads in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness equals approx. 10 mm
- characterized by smoothness
- with direct contact (without coatings)
- during pulling in a direction vertical to the plane
- at room temperature
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Beware of splinters
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Magnetic interference
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.
Fire risk
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Hand protection
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Threat to electronics
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Keep away from children
These products are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Handling rules
Be careful. Neodymium magnets act from a distance and connect with massive power, often faster than you can react.
Allergic reactions
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and opt for versions in plastic housing.
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Implant safety
Individuals with a ICD have to maintain an large gap from magnets. The magnetic field can stop the operation of the implant.
