Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (according to research),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- Thanks to the metallic finish, the plating of nickel, gold-plated, or silver gives an professional appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Due to the potential of accurate molding and adaptation to unique solutions, neodymium magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
- Wide application in modern industrial fields – they find application in data components, electromotive mechanisms, medical equipment, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these magnets can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- with an ideally smooth contact surface
- without any air gap between the magnet and steel
- during detachment in a direction vertical to the plane
- at room temperature
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be escaped to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.
Medical implants
Individuals with a ICD should maintain an large gap from magnets. The magnetism can stop the functioning of the implant.
Safe operation
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Physical harm
Big blocks can smash fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Threat to navigation
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
No play value
Neodymium magnets are not intended for children. Accidental ingestion of several magnets can lead to them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Fire warning
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Power loss in heat
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Keep away from computers
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
