Advantages and disadvantages of rare earth magnets.
Pros
- Their power is durable, and after around 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- In other words, due to the glossy finish of nickel, the element gains a professional look,
- Magnetic induction on the working part of the magnet is strong,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in constructing and the capacity to customize to complex applications,
- Fundamental importance in advanced technology sectors – they are commonly used in hard drives, electric motors, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness of at least 10 mm
- characterized by smoothness
- with zero gap (no coatings)
- under perpendicular force vector (90-degree angle)
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (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 generating force.
- Chemical composition of the base – mild steel gives the best results. Alloy steels decrease magnetic properties and holding force.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Respect the power
Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.
Adults only
NdFeB magnets are not toys. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Medical interference
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Eye protection
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them breaking into shards.
Warning for allergy sufferers
Some people experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching may cause an allergic reaction. We suggest use protective gloves.
Dust explosion hazard
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Impact on smartphones
Remember: rare earth magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and GPS.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
Finger safety
Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
