Strengths as well as weaknesses of neodymium magnets.
Pros
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
- A magnet with a smooth nickel surface has better aesthetics,
- Magnets are characterized by huge magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of flexible forming and customization to specialized projects, neodymium magnets can be produced in a broad palette of forms and dimensions, which amplifies use scope,
- Significant place in high-tech industry – they are used in magnetic memories, drive modules, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease 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 recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of producing threads in the magnet and complex shapes - preferred is a housing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what affects it?
- using a base made of mild steel, serving as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- with total lack of distance (without paint)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and holding force.
- Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Protective goggles
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Permanent damage
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Physical harm
Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Magnetic interference
A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Life threat
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Protect data
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Choking Hazard
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.
Flammability
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Handling guide
Exercise caution. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.
