Strengths and weaknesses of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well resist against demagnetization caused by foreign field sources,
- Thanks to the metallic finish, the plating of nickel, gold, or silver gives an clean appearance,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the ability to customize to individual projects,
- Huge importance in innovative solutions – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Determinants of lifting force in real conditions
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Handling rules
Handle magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their force.
No play value
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
Flammability
Powder created during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Impact on smartphones
Note: rare earth magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Health Danger
People with a heart stimulator have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.
Operating temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Physical harm
Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
Data carriers
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
