Pros and cons of neodymium magnets.
Strengths
- They retain full power for nearly ten years – the drop is just ~1% (according to analyses),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external interference,
- By applying a smooth coating of silver, the element has an proper look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- 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 the potential of flexible shaping and adaptation to specialized solutions, NdFeB magnets can be created in a variety of geometric configurations, which amplifies use scope,
- Key role in innovative solutions – they are commonly used in computer drives, electric drive systems, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- without the slightest air gap between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped to the other side.
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact and select coated magnets.
Threat to electronics
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Handling guide
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Combustion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Threat to navigation
Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, tablet, and GPS.
Magnets are brittle
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Crushing risk
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Keep away from children
Neodymium magnets are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.
Danger to pacemakers
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
