Pros and cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They show high resistance to demagnetization induced by external disturbances,
- By using a lustrous layer of silver, the element has an professional look,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom shaping and adapting to concrete requirements,
- Key role in future technologies – they serve a role in hard drives, brushless drives, advanced medical instruments, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- with a cross-section of at least 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Practical aspects of lifting capacity – factors
- Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Fragile material
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
No play value
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Keep away from computers
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Flammability
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Nickel allergy
Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact and choose coated magnets.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Phone sensors
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Crushing risk
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
