Pros and cons of neodymium magnets.
Advantages
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They retain 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,
- Magnetic induction on the surface of the magnet turns out to be strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the ability to customize to complex applications,
- Huge importance in innovative solutions – they serve a role in hard drives, brushless drives, medical devices, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making nuts in the magnet and complex forms - preferred is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets 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
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of structural steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into shards.
GPS and phone interference
A strong magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.
Safe distance
Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Product not for children
Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from children and animals.
Crushing force
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Power loss in heat
Avoid heat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Fire warning
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Nickel allergy
Some people have a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause skin redness. We strongly advise use safety gloves.
Warning for heart patients
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Immense force
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
