Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around ten years – the drop is just ~1% (according to analyses),
- They maintain their magnetic properties even under external field action,
- In other words, due to the aesthetic surface of silver, the element looks attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in constructing and the ability to customize to individual projects,
- Key role in future technologies – they are used in mass storage devices, electric motors, advanced medical instruments, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate does not close the flux, causing part of the flux to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Product not for children
These products are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Immense force
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Warning for allergy sufferers
Some people suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in an allergic reaction. We suggest wear protective gloves.
Mechanical processing
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Safe distance
Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Heat warning
Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Crushing risk
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Precision electronics
Remember: rare earth magnets generate a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.
