Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- Their power is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are highly resistant to loss of magnetic properties caused by magnetic disturbances,
- By applying a decorative layer of gold, the element presents an professional look,
- They feature high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Thanks to versatility in shaping and the capacity to customize to complex applications,
- Huge importance in electronics industry – they find application in hard drives, electromotive mechanisms, precision medical tools, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Limitations
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 resistant to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished touching surface
- without any clearance between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
Material brittleness
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Adults only
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.
Dust is flammable
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Hand protection
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Nickel coating and allergies
A percentage of the population have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. We strongly advise use safety gloves.
Pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Magnetic interference
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Permanent damage
Avoid heat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Safe operation
Be careful. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.
