Advantages and disadvantages of rare earth magnets.
Pros
- They do not lose power, even over around 10 years – the decrease in power is only ~1% (based on measurements),
- They retain their magnetic properties even under external field action,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Thanks to freedom in constructing and the capacity to modify to individual projects,
- Wide application in future technologies – they are used in HDD drives, electric drive systems, medical equipment, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- under vertical force vector (90-degree angle)
- at standard ambient temperature
What influences lifting capacity in practice
- Air gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Life threat
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them shattering into shards.
This is not a toy
These products are not toys. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Handling guide
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Bone fractures
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Sensitization to coating
A percentage of the population have a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We strongly advise wear protective gloves.
Keep away from electronics
Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Mechanical processing
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
