Magnetic properties of material
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Strengths and weaknesses of neodymium magnets.
Besides their high retention, neodymium magnets are valued for these benefits:
- They do not lose strength, even during around 10 years – the decrease in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- A magnet with a smooth nickel surface has better aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Due to the ability of free molding and adaptation to custom projects, NdFeB magnets can be created in a variety of geometric configurations, which amplifies use scope,
- Universal use in innovative solutions – they are used in mass storage devices, electric drive systems, medical equipment, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages of NdFeB magnets:
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force 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 during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Maximum lifting force for a neodymium magnet – what contributes to it?
The lifting capacity listed is a measurement result conducted under standard conditions:
- using a plate made of mild steel, acting as a ideal flux conductor
- with a cross-section of at least 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Lifting capacity in real conditions – factors
In practice, the actual lifting capacity results from many variables, listed from the most important:
- Air gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
* Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap {between} the magnet’s surface and the plate reduces the load capacity.
Warnings
Dust is flammable
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Demagnetization risk
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Crushing force
Big blocks can break fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact or choose encased magnets.
Life threat
Patients with a ICD should maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
No play value
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
Beware of splinters
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Protect data
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Respect the power
Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their power.
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
