Advantages and disadvantages of rare earth magnets.
Pros
- They do not lose power, even after approximately 10 years – the reduction in power is only ~1% (based on measurements),
- They are resistant to demagnetization induced by external disturbances,
- A magnet with a smooth nickel surface has an effective appearance,
- Magnets are distinguished by very high magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to the potential of free molding and adaptation to unique solutions, magnetic components can be created in a broad palette of forms and dimensions, which makes them more universal,
- Key role in innovative solutions – they serve a role in HDD drives, brushless drives, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems
Weaknesses
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished contact surface
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Key elements affecting lifting force
- Gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Finger safety
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Nickel coating and allergies
Certain individuals have a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. We suggest wear protective gloves.
Warning for heart patients
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
No play value
NdFeB magnets are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.
Respect the power
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Phone sensors
A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid damaging the sensors.
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Dust is flammable
Dust generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
