Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under external field action,
- Thanks to the metallic finish, the plating of nickel, gold, or silver-plated gives an clean appearance,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in forming and the ability to adapt to complex applications,
- Huge importance in future technologies – they serve a role in data components, electromotive mechanisms, medical equipment, and technologically advanced constructions.
- Compactness – despite small sizes they generate large force, 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 steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- without the slightest air gap between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
What influences lifting capacity in practice
- Clearance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Data carriers
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Maximum temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Pinching danger
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!
Nickel coating and allergies
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or choose coated magnets.
Fire risk
Powder created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Keep away from electronics
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
Health Danger
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Choking Hazard
These products are not toys. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Handling guide
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
