Advantages as well as disadvantages of rare earth magnets.
Benefits
- They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
- Magnets very well defend themselves against loss of magnetization caused by external fields,
- Thanks to the reflective finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- Magnets are characterized by huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Considering the potential of accurate forming and customization to specialized solutions, NdFeB magnets can be produced in a wide range of forms and dimensions, which makes them more universal,
- Wide application in innovative solutions – they are commonly used in mass storage devices, electric drive systems, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of making nuts in the magnet and complicated forms - preferred is cover - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of low-carbon steel, acting as a magnetic yoke
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Key elements affecting lifting force
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Protect data
Device Safety: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Compass and GPS
A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Allergy Warning
Studies show that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for versions in plastic housing.
Fire warning
Powder produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Shattering risk
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Pacemakers
People with a ICD should maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Demagnetization risk
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Handling rules
Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and respect their force.
Choking Hazard
These products are not intended for children. Eating a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.
Serious injuries
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
