Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- By using a smooth layer of nickel, the element presents an aesthetic look,
- Magnets are characterized by maximum magnetic induction on the active area,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the ability of accurate forming and customization to individualized solutions, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they serve a role in HDD drives, motor assemblies, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making nuts in the magnet and complex shapes - recommended is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- with total lack of distance (without coatings)
- during detachment in a direction vertical to the plane
- at room temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Heat – neodymium magnets 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 was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
No play value
NdFeB magnets are not toys. Eating multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Pinching danger
Big blocks can crush fingers instantly. Do not put your hand betwixt two attracting surfaces.
Precision electronics
An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Nickel coating and allergies
Certain individuals have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause dermatitis. We strongly advise wear safety gloves.
Protect data
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Do not underestimate power
Handle magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.
Fire warning
Powder generated during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Medical interference
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
