Strengths and weaknesses of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They maintain their magnetic properties even under strong external field,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual creating and adjusting to concrete needs,
- Fundamental importance in modern industrial fields – they are commonly used in hard drives, electric drive systems, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 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 as well as corrosion.
- Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a thickness no less than 10 mm
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
H&S for magnets
No play value
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Fire risk
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Threat to navigation
A powerful magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Avoid contact if allergic
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact and opt for versions in plastic housing.
Protect data
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Crushing risk
Large magnets can crush fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Risk of cracking
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Medical implants
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Handling rules
Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their power.
