Advantages and disadvantages of neodymium magnets.
Advantages
- Their magnetic field is maintained, and after around 10 years it decreases only by ~1% (according to research),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the metallic surface of nickel, the element gains visual value,
- They show high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to the option of flexible shaping and customization to individualized needs, magnetic components can be modeled in a wide range of shapes and sizes, which increases their versatility,
- Wide application in advanced technology sectors – they are used in mass storage devices, brushless drives, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects 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 extremely resistant to heat
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- using a plate made of mild steel, functioning as a magnetic yoke
- with a cross-section minimum 10 mm
- characterized by even structure
- without any clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Swallowing risk
Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
Allergic reactions
A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. We suggest use protective gloves.
Operating temperature
Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Bodily injuries
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Dust explosion hazard
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Immense force
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and respect their power.
Phone sensors
Note: rare earth magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Threat to electronics
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Protective goggles
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them shattering into small pieces.
