Strengths as well as weaknesses of neodymium magnets.
Pros
- They retain attractive force for almost ten years – the loss is just ~1% (according to analyses),
- Neodymium magnets are distinguished by extremely resistant to demagnetization caused by external field sources,
- By applying a lustrous layer of nickel, the element presents an elegant look,
- Neodymium magnets generate maximum magnetic induction on a small surface, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to modularity in forming and the capacity to modify to unusual requirements,
- Significant place in high-tech industry – they are commonly used in data components, electric motors, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of making nuts in the magnet and complex forms - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a cross-section minimum 10 mm
- with an polished contact surface
- with direct contact (without coatings)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
What influences lifting capacity in practice
- Clearance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
No play value
Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
Powerful field
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Do not drill into magnets
Dust generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Protect data
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Compass and GPS
Remember: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
ICD Warning
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Finger safety
Large magnets can crush fingers instantly. Do not place your hand between two strong magnets.
Heat warning
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Metal Allergy
Some people have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause skin redness. We strongly advise use safety gloves.
