Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- They are resistant to demagnetization induced by external magnetic fields,
- Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- In view of the option of precise forming and adaptation to unique solutions, NdFeB magnets can be modeled in a wide range of forms and dimensions, which expands the range of possible applications,
- Versatile presence in innovative solutions – they are used in computer drives, electric motors, diagnostic systems, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- under axial force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Skin irritation risks
A percentage of the population suffer from a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. We recommend use protective gloves.
This is not a toy
Neodymium magnets are not suitable for play. Swallowing several magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Cards and drives
Do not bring magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them breaking into small pieces.
Physical harm
Large magnets can break fingers instantly. Do not put your hand between two strong magnets.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Implant safety
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Safe operation
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
