Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- 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...
- In view of the possibility of flexible molding and adaptation to specialized projects, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Significant place in future technologies – they are utilized in hard drives, motor assemblies, medical equipment, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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 magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted into the air.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Handling guide
Be careful. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and wear gloves.
Magnetic interference
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Protect data
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Maximum temperature
Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.
This is not a toy
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
Crushing risk
Large magnets can break fingers instantly. Do not place your hand between two attracting surfaces.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them breaking into small pieces.
Machining danger
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
