Pros and cons of Nd2Fe14B magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They do not lose power, even after nearly 10 years – the reduction in strength is only ~1% (theoretically),
  • They feature excellent resistance to magnetism drop due to external magnetic sources,
  • By covering with a decorative coating of nickel, the element acquires an aesthetic look,
  • The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to versatility in constructing and the capacity to modify to unusual requirements,
  • Universal use in modern industrial fields – they are commonly used in mass storage devices, electric drive systems, diagnostic systems, as well as technologically advanced constructions.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium magnets lose 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 corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices can 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

Highest magnetic holding force – what affects it?

Information about lifting capacity was defined for ideal contact conditions, taking into account:
  • using a sheet made of mild steel, functioning as a ideal flux conductor
  • whose transverse dimension is min. 10 mm
  • with an polished contact surface
  • with zero gap (without paint)
  • during detachment in a direction perpendicular to the plane
  • at standard ambient temperature

Lifting capacity in practice – influencing factors

In real-world applications, the real power is determined by many variables, presented from crucial:
  • Gap (between the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
  • Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
  • Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
  • Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets
Bone fractures

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!

Heat warning

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Nickel coating and allergies

Some people have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in an allergic reaction. We strongly advise wear safety gloves.

Keep away from children

Neodymium magnets are not intended for children. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.

Safe operation

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

Precision electronics

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Medical interference

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Shattering risk

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Protect data

Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Combustion hazard

Powder produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
