Other offers
Pros as well as cons of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the smooth layer of nickel, the element is aesthetically pleasing,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to freedom in shaping and the capacity to modify to unusual requirements,
- Key role in advanced technology sectors – they are utilized in hard drives, drive modules, medical devices, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- 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.
- Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a plane cleaned and smooth
- with direct contact (without coatings)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Magnet lifting force in use – key factors
- Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Compass and GPS
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Conscious usage
Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their power.
Product not for children
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from children and animals.
Do not drill into magnets
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Warning for heart patients
Individuals with a pacemaker have to maintain an large gap from magnets. The magnetism can stop the functioning of the life-saving device.
Electronic devices
Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and use protective gear.
Material brittleness
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them cracking into shards.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Maximum temperature
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
