Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
- A magnet with a shiny gold surface has an effective appearance,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- 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 option of flexible shaping and adaptation to custom requirements, neodymium magnets can be manufactured in a wide range of forms and dimensions, which makes them more universal,
- Versatile presence in modern industrial fields – they are utilized in computer drives, drive modules, medical equipment, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a sheet made of mild steel, serving as a magnetic yoke
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be escaped into the air.
- Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – 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 carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Handling rules
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can react.
Combustion hazard
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Finger safety
Pinching hazard: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Operating temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Keep away from children
Always keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.
Eye protection
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Compass and GPS
An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Keep magnets near a device to prevent damaging the sensors.
Nickel coating and allergies
Some people experience a sensitization to nickel, which is the common plating for NdFeB magnets. Prolonged contact may cause skin redness. It is best to use protective gloves.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Magnetic media
Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
