Strengths as well as weaknesses of neodymium magnets.
Advantages
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- Thanks to the metallic finish, the plating of nickel, gold, or silver-plated gives an professional appearance,
- Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
- 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...
- Thanks to the possibility of accurate shaping and adaptation to custom requirements, neodymium magnets can be produced in a broad palette of shapes and sizes, which makes them more universal,
- Versatile presence in high-tech industry – they serve a role in data components, brushless drives, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer 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
- 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
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Nickel allergy
Some people suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We strongly advise use protective gloves.
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Implant safety
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Serious injuries
Danger of trauma: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Threat to navigation
Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Fire warning
Powder produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Threat to electronics
Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Shattering risk
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Swallowing risk
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are very dangerous.
