Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetism drop when exposed to external fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the ability to adapt to client solutions,
- Versatile presence in future technologies – they are commonly used in hard drives, brushless drives, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be escaped into the air.
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Life threat
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Heat sensitivity
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Material brittleness
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Magnetic media
Do not bring magnets near a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Magnetic interference
Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, device, and GPS.
Immense force
Handle with care. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Skin irritation risks
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, refrain from direct skin contact or choose versions in plastic housing.
Product not for children
Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Crushing risk
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
