Pros as well as cons of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They show high resistance to demagnetization induced by external field influence,
- A magnet with a metallic nickel surface has better aesthetics,
- They show high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the capacity to adapt to individual projects,
- Huge importance in modern industrial fields – they find application in data components, electromotive mechanisms, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Limitations
- They are prone to damage 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 force. 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a sheet made of mild steel, functioning as a magnetic yoke
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Product not for children
These products are not toys. Swallowing multiple magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Electronic hazard
Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
GPS and phone interference
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Do not overheat magnets
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Combustion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Allergic reactions
Certain individuals experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause skin redness. We strongly advise use safety gloves.
Pacemakers
Patients with a ICD have to keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Safe operation
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Bodily injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
