Advantages as well as disadvantages of neodymium magnets.
Strengths
- Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They retain their magnetic properties even under close interference source,
- Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- 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 flexibility in forming and the ability to adapt to specific needs,
- Universal use in modern industrial fields – they find application in mass storage devices, drive modules, medical equipment, as well as industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- at temperature room level
Practical lifting capacity: influencing factors
- Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Handling guide
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.
Combustion hazard
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from children and animals.
Crushing force
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or opt for versions in plastic housing.
Demagnetization risk
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Danger to pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Threat to electronics
Do not bring magnets near a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Compass and GPS
Navigation devices and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Eye protection
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them shattering into small pieces.
