Strengths as well as weaknesses of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- By applying a reflective layer of gold, the element acquires an professional look,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- 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...
- Thanks to modularity in constructing and the ability to customize to client solutions,
- Versatile presence in modern technologies – they are used in data components, drive modules, advanced medical instruments, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (without coatings)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Finger safety
Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Powerful field
Handle magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their force.
Material brittleness
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Nickel allergy
Certain individuals experience a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause dermatitis. It is best to use protective gloves.
Phone sensors
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.
Do not give to children
Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are very dangerous.
Machining danger
Powder created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Medical interference
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Safe distance
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
