Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a metallic silver surface has better aesthetics,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the potential of precise molding and adaptation to unique projects, neodymium magnets can be produced in a variety of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in advanced technology sectors – they find application in data components, brushless drives, advanced medical instruments, also industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience 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
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- with a cross-section of at least 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Key elements affecting lifting force
- Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Heat – 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 testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Respect the power
Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Fire warning
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
GPS and phone interference
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Product not for children
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Crushing risk
Large magnets can break fingers instantly. Do not place your hand betwixt two attracting surfaces.
Operating temperature
Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Protect data
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Nickel coating and allergies
A percentage of the population experience a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling may cause an allergic reaction. We suggest wear protective gloves.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into shards.
Implant safety
People with a pacemaker must maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.
