Pros as well as cons of Nd2Fe14B magnets.
Advantages
- Their power is maintained, and after around 10 years it drops only by ~1% (according to research),
- Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
- By using a decorative layer of silver, the element acquires an aesthetic look,
- Magnets are characterized by exceptionally strong magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the option of free forming and customization to individualized solutions, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they are commonly used in hard drives, electric motors, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can 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
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of mild steel, acting as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- in stable room temperature
Magnet lifting force in use – key factors
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Pinching danger
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Avoid contact if allergic
A percentage of the population have a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to dermatitis. We suggest wear safety gloves.
Safe distance
Do not bring magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Fire risk
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Fragile material
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Compass and GPS
A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.
Conscious usage
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Swallowing risk
Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.
Medical interference
People with a pacemaker have to keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Demagnetization risk
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
