Strengths and weaknesses of rare earth magnets.
Benefits
- They do not lose magnetism, even over around ten years – the reduction in lifting capacity is only ~1% (according to tests),
- Magnets effectively defend themselves against loss of magnetization caused by external fields,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnets exhibit exceptionally strong magnetic induction on the working surface,
- 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...
- Due to the potential of precise forming and customization to custom projects, magnetic components can be created in a broad palette of forms and dimensions, which makes them more universal,
- Universal use in electronics industry – they are utilized in HDD drives, brushless drives, precision medical tools, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- with total lack of distance (without impurities)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Crushing force
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Threat to navigation
An intense magnetic field interferes with the functioning of compasses in phones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.
Metal Allergy
Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or select versions in plastic housing.
Fire warning
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
This is not a toy
These products are not toys. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Keep away from computers
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Handling guide
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
