Pros and cons of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- Thanks to the shiny finish, the layer of nickel, gold-plated, or silver gives an modern appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- 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 versatility in forming and the ability to modify to complex applications,
- Key role in innovative solutions – they find application in HDD drives, electric motors, diagnostic systems, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with neodymium magnets
Respect the power
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Do not drill into magnets
Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Allergic reactions
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, prevent direct skin contact and opt for coated magnets.
Material brittleness
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Electronic devices
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Physical harm
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Adults only
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Pacemakers
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Demagnetization risk
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Compass and GPS
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
