Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their power is durable, and after approximately ten years it drops only by ~1% (according to research),
- Magnets perfectly protect themselves against loss of magnetization caused by external fields,
- A magnet with a smooth nickel surface has an effective appearance,
- Magnets possess maximum magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in shaping and the capacity to customize to client solutions,
- Versatile presence in electronics industry – they are used in mass storage devices, brushless drives, advanced medical instruments, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of making threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, 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 budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with total lack of distance (without paint)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Bone fractures
Big blocks can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Medical interference
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Protect data
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Protective goggles
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Caution required
Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.
No play value
Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Operating temperature
Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Mechanical processing
Powder produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Keep away from electronics
A strong magnetic field disrupts the functioning of compasses in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.
