Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain full power for nearly 10 years – the loss is just ~1% (according to analyses),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the plating of nickel, gold, or silver gives an professional appearance,
- Magnets exhibit very high magnetic induction on the active area,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the capacity to customize to specific needs,
- Wide application in future technologies – they are utilized in data components, motor assemblies, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these products can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of mild steel, acting as a magnetic yoke
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Smoothness – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Warnings
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.
Pacemakers
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Do not underestimate power
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Product not for children
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Power loss in heat
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Protective goggles
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Phone sensors
A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
