Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
- A magnet with a shiny gold surface looks better,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the option of flexible forming and customization to specialized requirements, NdFeB magnets can be modeled in a variety of forms and dimensions, which makes them more universal,
- Versatile presence in high-tech industry – they serve a role in computer drives, electric drive systems, medical devices, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems
Cons
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- under axial force direction (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin plate does not accept the full field, causing part of the power to be wasted to the other side.
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Magnet fragility
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Phone sensors
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.
This is not a toy
These products are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.
Immense force
Handle with care. Neodymium magnets act from a distance and snap with huge force, often faster than you can move away.
Crushing force
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Protect data
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Avoid contact if allergic
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or select versions in plastic housing.
