Pros and cons of neodymium magnets.
Advantages
- Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets remain highly resistant to demagnetization caused by external interference,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the ability to customize to specific needs,
- Wide application in advanced technology sectors – they are utilized in mass storage devices, motor assemblies, precision medical tools, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Brittleness 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 suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by even structure
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Risk of cracking
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Safe distance
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Adults only
Always keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and select versions in plastic housing.
Operating temperature
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Bodily injuries
Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Mechanical processing
Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Implant safety
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Handling guide
Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.
Magnetic interference
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
