Pros as well as cons of neodymium magnets.
Advantages
- They retain attractive force for almost 10 years – the drop is just ~1% (based on simulations),
- They retain their magnetic properties even under strong external field,
- A magnet with a metallic nickel surface is more attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise shaping as well as optimizing to defined requirements,
- Versatile presence in future technologies – they are commonly used in computer drives, motor assemblies, medical devices, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. 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 strength. 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 advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- 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 is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- under conditions of no distance (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot 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 optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Immense force
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Precision electronics
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Serious injuries
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Adults only
Always keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Medical implants
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Safe distance
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
