Pros and cons of neodymium magnets.
Benefits
- Their strength is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external magnetic fields,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
- Magnets are characterized by very high magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- In view of the option of accurate shaping and adaptation to custom needs, magnetic components can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Versatile presence in future technologies – they are used in HDD drives, drive modules, medical devices, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- with zero gap (no coatings)
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Product not for children
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from children and animals.
Do not underestimate power
Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.
Impact on smartphones
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Protect data
Avoid bringing magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Power loss in heat
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Warning for heart patients
For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Bodily injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Skin irritation risks
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or select versions in plastic housing.
Dust is flammable
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Fragile material
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
