Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after around ten years it decreases only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- In other words, due to the shiny surface of nickel, the element gains a professional look,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by very 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 freedom in forming and the ability to modify to individual projects,
- Universal use in advanced technology sectors – they find application in data components, brushless drives, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises 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 force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Key elements affecting lifting force
- Distance – existence of any layer (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Steel type – low-carbon steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Machining danger
Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Implant safety
Individuals with a pacemaker have to keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
Safe distance
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Precision electronics
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Operating temperature
Do not overheat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Keep away from children
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Bodily injuries
Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
