Strengths and weaknesses of neodymium magnets.
Pros
- Their strength is maintained, and after around 10 years it drops only by ~1% (according to research),
- They do not lose their magnetic properties even under strong external field,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the top side of the magnet is strong,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the option of flexible molding and customization to individualized needs, neodymium magnets can be produced in a wide range of forms and dimensions, which makes them more universal,
- Wide application in future technologies – they are used in data components, brushless drives, medical devices, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- 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?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- characterized by smoothness
- with zero gap (without paint)
- under perpendicular force direction (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Clearance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Maximum temperature
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Pinching danger
Big blocks can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Danger to pacemakers
Patients with a pacemaker have to keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Magnetic media
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Respect the power
Handle with care. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can move away.
GPS Danger
A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Keep away from children
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them shattering into shards.
