Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the smooth surface of silver, the element gains visual value,
- Magnetic induction on the surface of the magnet turns out to be very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to flexibility in designing and the ability to modify to complex applications,
- Universal use in modern industrial fields – they are commonly used in data components, motor assemblies, diagnostic systems, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- with direct contact (without coatings)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Adults only
Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.
Combustion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Nickel allergy
A percentage of the population have a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. We suggest use protective gloves.
Eye protection
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Impact on smartphones
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Conscious usage
Use magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and respect their force.
Thermal limits
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Crushing risk
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Electronic hazard
Do not bring magnets close to a purse, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
