Strengths and weaknesses of neodymium magnets.
Pros
- Their strength remains stable, and after around 10 years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss due to external fields,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the top side of the magnet remains impressive,
- 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 freedom in forming and the capacity to customize to complex applications,
- Huge importance in innovative solutions – they are commonly used in data components, electromotive mechanisms, medical devices, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 very 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 stable to moisture, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without the slightest clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Electronic devices
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose versions in plastic housing.
Permanent damage
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Threat to navigation
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Do not give to children
Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.
Bone fractures
Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Warning for heart patients
People with a ICD must keep an absolute distance from magnets. The magnetism can stop the operation of the implant.
Fire risk
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
