Advantages and disadvantages of neodymium magnets.
Pros
- Their strength is maintained, and after around ten years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under strong external field,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by huge magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of accurate modeling as well as optimizing to complex requirements,
- Fundamental importance in innovative solutions – they serve a role in mass storage devices, electromotive mechanisms, medical devices, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating threads and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a plate made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with direct contact (without coatings)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
What influences lifting capacity in practice
- Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Operating temperature – 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 testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and opt for versions in plastic housing.
Hand protection
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Safe operation
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.
Fragile material
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Heat sensitivity
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Compass and GPS
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Medical implants
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Flammability
Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Keep away from children
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Safe distance
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).
