Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by external field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have very high magnetic induction on the outer side,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Considering the option of precise forming and adaptation to specialized needs, neodymium magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Key role in modern technologies – they are utilized in hard drives, drive modules, advanced medical instruments, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Warnings
Do not drill into magnets
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Adults only
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of children and animals.
Medical implants
Patients with a heart stimulator must maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Nickel allergy
A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in dermatitis. We recommend use protective gloves.
Beware of splinters
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Threat to navigation
Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Immense force
Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Serious injuries
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
