Pros and cons of neodymium magnets.
Pros
- They do not lose magnetism, even over nearly ten years – the drop in power is only ~1% (theoretically),
- Magnets perfectly resist against demagnetization caused by external fields,
- By covering with a shiny coating of nickel, the element has an elegant look,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of detailed forming as well as adapting to concrete applications,
- Significant place in modern technologies – they serve a role in HDD drives, drive modules, diagnostic systems, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of producing nuts in the magnet and complicated forms - preferred is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a base made of low-carbon steel, functioning as a circuit closing element
- whose thickness equals approx. 10 mm
- with an ideally smooth contact surface
- under conditions of no distance (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Mechanical processing
Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Do not overheat magnets
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for encased magnets.
Shattering risk
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.
Do not give to children
Only for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Pacemakers
People with a ICD should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the implant.
Threat to electronics
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Serious injuries
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Threat to navigation
An intense magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.
