Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external magnetic fields,
- Thanks to the smooth finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- Magnetic induction on the surface of the magnet is extremely intense,
- 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...
- Considering the potential of precise molding and customization to unique needs, neodymium magnets can be created in a broad palette of forms and dimensions, which makes them more universal,
- Key role in electronics industry – they are used in HDD drives, brushless drives, medical devices, also industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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, when using outdoors
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- using a sheet made of mild steel, functioning as a circuit closing element
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them cracking into small pieces.
Electronic hazard
Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and wear gloves.
Powerful field
Be careful. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.
Mechanical processing
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Heat sensitivity
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Do not give to children
Always keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are very dangerous.
Pacemakers
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Hand protection
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
