Other products
Pros as well as cons of rare earth magnets.
Pros
- They retain full power for almost 10 years – the drop is just ~1% (according to analyses),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet is strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the option of accurate shaping and adaptation to specialized projects, NdFeB magnets can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Key role in electronics industry – they are commonly used in hard drives, electromotive mechanisms, medical equipment, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (without paint)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Do not underestimate power
Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and do not underestimate their force.
Bodily injuries
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Material brittleness
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and select coated magnets.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Phone sensors
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
Choking Hazard
Neodymium magnets are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires immediate surgery.
Implant safety
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Electronic hazard
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
