Pros and cons of neodymium magnets.
Pros
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
- By applying a shiny coating of silver, the element acquires an elegant look,
- Magnets are characterized by very high magnetic induction on the surface,
- 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 modularity in forming and the capacity to customize to client solutions,
- Fundamental importance in future technologies – they serve a role in computer drives, electromotive mechanisms, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their force 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 stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- whose thickness reaches at least 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- at standard ambient temperature
Key elements affecting lifting force
- Gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with neodymium magnets
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Pacemakers
Individuals with a heart stimulator should maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.
Eye protection
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Powerful field
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Mechanical processing
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Finger safety
Large magnets can smash fingers in a fraction of a second. Do not put your hand between two strong magnets.
Adults only
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
Allergy Warning
Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands and select coated magnets.
Cards and drives
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Precision electronics
A powerful magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to prevent breaking the sensors.
