Advantages and disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets are highly resistant to demagnetization caused by external magnetic fields,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnetic induction on the surface of the magnet remains very high,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to flexibility in forming and the ability to customize to complex applications,
- Fundamental importance in advanced technology sectors – they find application in hard drives, motor assemblies, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Cons
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power 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
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
- 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
Maximum holding power of the magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- without any insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of lifting force in real conditions
- Clearance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Medical interference
Patients with a ICD must keep an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Allergy Warning
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and opt for versions in plastic housing.
Handling rules
Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
Swallowing risk
NdFeB magnets are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Power loss in heat
Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Phone sensors
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Fire warning
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Pinching danger
Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Protect data
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Protective goggles
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
