Field Strength

Strengths and weaknesses of Nd2Fe14B magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They do not lose power, even over approximately ten years – the drop in strength is only ~1% (based on measurements),
  • They retain their magnetic properties even under external field action,
  • In other words, due to the reflective layer of nickel, the element looks attractive,
  • Magnets possess 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...
  • Possibility of exact creating as well as adapting to specific applications,
  • Key role in modern industrial fields – they serve a role in HDD drives, electromotive mechanisms, medical devices, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems

Weaknesses

Cons 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, as well as 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 strength (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 extremely resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
  • Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical after entering the body.
  • Due to complex production process, their price is higher than average,

Lifting parameters

Maximum holding power of the magnet – what contributes to it?

Magnet power was determined for optimal configuration, including:
  • using a sheet made of mild steel, acting as a ideal flux conductor
  • with a cross-section of at least 10 mm
  • characterized by even structure
  • with zero gap (no paint)
  • under vertical force direction (90-degree angle)
  • at temperature room level

Practical aspects of lifting capacity – factors

Please note that the application force will differ influenced by elements below, in order of importance:
  • Air gap (between the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Steel thickness – too thin sheet does not close the flux, causing part of the flux to be escaped into the air.
  • Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
  • Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Safe handling of NdFeB magnets
No play value

Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are fatal.

Conscious usage

Use magnets consciously. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their force.

Physical harm

Large magnets can crush fingers instantly. Never put your hand between two strong magnets.

Warning for heart patients

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Skin irritation risks

A percentage of the population suffer from a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to a rash. We suggest use safety gloves.

GPS and phone interference

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.

Fire warning

Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Electronic hazard

Do not bring magnets close to a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Maximum temperature

Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Risk of cracking

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
