Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose strength, even during approximately ten years – the reduction in lifting capacity is only ~1% (theoretically),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the possibility of precise forming and adaptation to individualized solutions, neodymium magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Huge importance in advanced technology sectors – they find application in magnetic memories, motor assemblies, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of mild steel, serving as a magnetic yoke
- with a thickness minimum 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – the best choice is high-permeability steel. Stainless steels may attract less.
- Surface structure – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
GPS Danger
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Cards and drives
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Shattering risk
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Choking Hazard
These products are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, cease handling magnets and use protective gear.
Physical harm
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Health Danger
Individuals with a ICD must maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Demagnetization risk
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
