Pros and cons of neodymium magnets.
Advantages
- They do not lose strength, even during nearly 10 years – the decrease in strength is only ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the glossy finish of nickel, the element looks attractive,
- Magnetic induction on the top side of the magnet remains strong,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in constructing and the capacity to modify to individual projects,
- Key role in modern industrial fields – they are commonly used in magnetic memories, drive modules, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 ability of producing nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process 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 plate made of high-permeability steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and wear gloves.
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Operating temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Adults only
Neodymium magnets are not toys. Swallowing a few magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Pinching danger
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Electronic hazard
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Implant safety
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Impact on smartphones
An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to prevent damaging the sensors.
Immense force
Be careful. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can move away.
Flammability
Powder created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
