Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external interference,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- 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 the potential of accurate molding and customization to individualized projects, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which makes them more universal,
- Wide application in advanced technology sectors – they find application in mass storage devices, electric drive systems, precision medical tools, and modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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 advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- with an polished contact surface
- with direct contact (no impurities)
- under vertical force direction (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost to the other side.
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Magnetic media
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
GPS Danger
An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
Material brittleness
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them shattering into small pieces.
Crushing force
Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
Life threat
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Choking Hazard
Always keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Power loss in heat
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for coated magnets.
Caution required
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Do not drill into magnets
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
