Pros and cons of neodymium magnets.
Strengths
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They are resistant to demagnetization induced by external magnetic fields,
- In other words, due to the smooth finish of silver, the element looks attractive,
- Magnets are characterized by impressive magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the option of free forming and customization to specialized solutions, NdFeB magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
- Huge importance in electronics industry – they are utilized in computer drives, motor assemblies, diagnostic systems, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited ability of making threads in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- with direct contact (no paint)
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Determinants of lifting force in real conditions
- Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
GPS Danger
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Product not for children
Always keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Allergic reactions
Some people have a sensitization to nickel, which is the standard coating for neodymium magnets. Extended handling can result in dermatitis. It is best to wear safety gloves.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Do not drill into magnets
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Crushing risk
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Do not overheat magnets
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Health Danger
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Keep away from computers
Equipment safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
