Strengths as well as weaknesses of rare earth magnets.
Advantages
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a metallic gold surface has better aesthetics,
- Magnetic induction on the working layer of the magnet remains maximum,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact modeling and adjusting to concrete requirements,
- Versatile presence in high-tech industry – they serve a role in mass storage devices, electric drive systems, medical devices, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we recommend 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 power. Often, when the temperature exceeds 80°C, their strength 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 rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction vertical to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Metal Allergy
Some people have a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to an allergic reaction. We recommend use safety gloves.
Crushing risk
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
ICD Warning
Patients with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Flammability
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Handling guide
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Threat to electronics
Avoid bringing magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Power loss in heat
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Choking Hazard
Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
Magnet fragility
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Compass and GPS
Be aware: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, device, and navigation systems.
