Advantages and disadvantages of neodymium magnets.
Pros
- They retain full power for around 10 years – the loss is just ~1% (based on simulations),
- They retain their magnetic properties even under external field action,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- 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...
- Possibility of precise machining as well as modifying to specific requirements,
- Huge importance in advanced technology sectors – they are commonly used in computer drives, electromotive mechanisms, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- characterized by smoothness
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Warnings
Warning for heart patients
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Conscious usage
Handle magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their power.
Threat to electronics
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Phone sensors
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Product not for children
Always store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, prevent direct skin contact or opt for versions in plastic housing.
Hand protection
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Machining danger
Dust produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Heat sensitivity
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
