Pros as well as cons of Nd2Fe14B magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even after approximately 10 years – the decrease in strength is only ~1% (based on measurements),
  • They are extremely resistant to demagnetization induced by external magnetic fields,
  • In other words, due to the aesthetic surface of nickel, the element looks attractive,
  • Magnetic induction on the working layer of the magnet is impressive,
  • 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...
  • Possibility of detailed shaping and optimizing to defined conditions,
  • Huge importance in advanced technology sectors – they are utilized in HDD drives, drive modules, advanced medical instruments, as well as complex engineering applications.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets and proposals for their use:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making threads in the magnet and complicated shapes - preferred is casing - magnet mounting.
  • Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

The declared magnet strength refers to the limit force, obtained under ideal test conditions, namely:
  • using a plate made of high-permeability steel, serving as a magnetic yoke
  • whose transverse dimension equals approx. 10 mm
  • characterized by lack of roughness
  • without the slightest clearance between the magnet and steel
  • during detachment in a direction vertical to the plane
  • at standard ambient temperature

Magnet lifting force in use – key factors

It is worth knowing that the magnet holding may be lower depending on elements below, starting with the most relevant:
  • Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
  • Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Warnings
Electronic hazard

Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).

No play value

These products are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.

Compass and GPS

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Heat sensitivity

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Bone fractures

Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Sensitization to coating

A percentage of the population suffer from a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. We strongly advise use safety gloves.

Health Danger

Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.

Flammability

Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Risk of cracking

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them shattering into shards.

Respect the power

Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
