Field Strength

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:
  • Their strength is maintained, and after around 10 years it decreases only by ~1% (according to research),
  • They are noted for resistance to demagnetization induced by external disturbances,
  • A magnet with a smooth gold surface is more attractive,
  • Magnets are distinguished by huge magnetic induction on the outer layer,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • In view of the possibility of free molding and adaptation to custom needs, NdFeB magnets can be created in a variety of geometric configurations, which makes them more universal,
  • Significant place in innovative solutions – they find application in mass storage devices, electric drive systems, diagnostic systems, and other advanced devices.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited ability of creating nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
  • Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Detachment force of the magnet in optimal conditionswhat it depends on?

The load parameter shown represents the limit force, recorded under optimal environment, specifically:
  • on a base made of mild steel, optimally conducting the magnetic field
  • whose transverse dimension equals approx. 10 mm
  • characterized by even structure
  • without any insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at standard ambient temperature

What influences lifting capacity in practice

During everyday use, the actual lifting capacity results from many variables, listed from the most important:
  • Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Steel thickness – too thin plate does not close the flux, causing part of the power to be lost into the air.
  • Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
  • Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets
Electronic hazard

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Allergy Warning

A percentage of the population experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Extended handling might lead to a rash. We suggest use protective gloves.

Medical implants

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Adults only

Absolutely keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are very dangerous.

Powerful field

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Fire warning

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Heat sensitivity

Keep cool. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Crushing risk

Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Shattering risk

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

Magnetic interference

A strong magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets near a device to avoid damaging the sensors.
