Strengths and weaknesses of rare earth magnets.
Benefits
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- A magnet with a smooth nickel surface has better aesthetics,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- 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 versatility in shaping and the ability to modify to specific needs,
- Versatile presence in modern technologies – they are commonly used in HDD drives, drive modules, diagnostic systems, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize 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 extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- characterized by even structure
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
- Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Warnings
Bodily injuries
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Heat warning
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Medical interference
People with a heart stimulator should maintain an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Impact on smartphones
An intense magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a device to avoid breaking the sensors.
Risk of cracking
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them cracking into small pieces.
Skin irritation risks
A percentage of the population experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching can result in a rash. It is best to use protective gloves.
Keep away from computers
Do not bring magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Choking Hazard
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep away from kids and pets.
Fire risk
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Immense force
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
