Pros and cons of neodymium magnets.
Strengths
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a metallic nickel surface looks better,
- Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in shaping and the ability to customize to individual projects,
- Wide application in high-tech industry – they find application in computer drives, electric motors, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- 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
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a thickness of at least 10 mm to avoid saturation
- with an ground contact surface
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the plane
- at room temperature
Practical lifting capacity: influencing factors
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Implant safety
Patients with a ICD should keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Dust is flammable
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Skin irritation risks
A percentage of the population experience a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We strongly advise wear protective gloves.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Magnetic interference
Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Crushing force
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Handling guide
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Maximum temperature
Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Magnetic media
Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Product not for children
Adult use only. Small elements can be swallowed, causing serious injuries. Keep out of reach of children and animals.
