Advantages as well as disadvantages of neodymium magnets.
Pros
- Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- Thanks to the metallic finish, the coating of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Magnetic induction on the surface of the magnet turns out to be extremely intense,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the capacity to customize to client solutions,
- Key role in advanced technology sectors – they are used in mass storage devices, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in compact constructions
Weaknesses
- 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 increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength 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 suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth contact surface
- with zero gap (no impurities)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Implant safety
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Thermal limits
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Handling rules
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Do not drill into magnets
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Avoid contact if allergic
A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause a rash. We strongly advise wear protective gloves.
Phone sensors
An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.
Do not give to children
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Crushing force
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Protect data
Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Fragile material
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
