Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- Their power is durable, and after around 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external interference,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the ability to modify to individual projects,
- Key role in electronics industry – they find application in hard drives, electromotive mechanisms, medical equipment, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be wasted into the air.
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Keep away from computers
Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Adults only
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Medical implants
Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Dust is flammable
Dust generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Skin irritation risks
A percentage of the population suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause dermatitis. We strongly advise use safety gloves.
Shattering risk
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Handling rules
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Maximum temperature
Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
GPS Danger
An intense magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
Pinching danger
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
