Pros and cons of rare earth magnets.
Strengths
- They do not lose magnetism, even during nearly ten years – the drop in power is only ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- 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...
- Thanks to modularity in designing and the capacity to adapt to unusual requirements,
- Universal use in future technologies – they find application in data components, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Pacemakers
Patients with a pacemaker should maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Do not drill into magnets
Powder created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Respect the power
Exercise caution. Neodymium magnets act from a distance and connect with huge force, often faster than you can move away.
Crushing force
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Precision electronics
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Product not for children
Strictly keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are life-threatening.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Operating temperature
Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Keep away from computers
Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease working with magnets and use protective gear.
