Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to freedom in designing and the capacity to customize to unusual requirements,
- Versatile presence in high-tech industry – they serve a role in magnetic memories, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their strength 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 stability even at temperatures 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 stable to moisture, when using outdoors
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these products can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- with direct contact (no paint)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Safe operation
Handle with care. Rare earth magnets act from a long distance and snap with massive power, often faster than you can move away.
Threat to navigation
Note: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
Shattering risk
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Bodily injuries
Risk of injury: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Machining danger
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Allergy Warning
Certain individuals experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to a rash. It is best to wear protective gloves.
Heat warning
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Warning for heart patients
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
No play value
Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Protect data
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
