Strengths and weaknesses of rare earth magnets.
Advantages
- They retain attractive force for almost ten years – the loss is just ~1% (in theory),
- They retain their magnetic properties even under external field action,
- In other words, due to the glossy finish of nickel, the element gains a professional look,
- Magnets exhibit exceptionally strong magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the ability to modify to complex applications,
- Universal use in electronics industry – they are commonly used in HDD drives, motor assemblies, medical equipment, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend 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 experience a drop in power. 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
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic field
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Lifting capacity in real conditions – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Permanent damage
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Precision electronics
An intense magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.
Eye protection
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Protect data
Do not bring magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Nickel allergy
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact or choose encased magnets.
Swallowing risk
Absolutely keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.
Physical harm
Big blocks can break fingers instantly. Do not put your hand betwixt two attracting surfaces.
Mechanical processing
Powder generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
