Strengths as well as weaknesses of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under external field action,
- A magnet with a smooth silver surface has better aesthetics,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the ability to adapt to complex applications,
- Significant place in innovative solutions – they are used in computer drives, electromotive mechanisms, medical devices, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's 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 durability 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.
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension is min. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel does not accept the full field, causing part of the power to be escaped into the air.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Protective goggles
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Pacemakers
For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
Allergy Warning
Certain individuals have a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in an allergic reaction. We suggest wear safety gloves.
Flammability
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Hand protection
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Handling guide
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Cards and drives
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Do not give to children
Neodymium magnets are not intended for children. Eating multiple magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
GPS Danger
Note: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
