Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under external field action,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are characterized by maximum magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in shaping and the ability to adapt to client solutions,
- Wide application in advanced technology sectors – they serve a role in magnetic memories, brushless drives, medical devices, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- 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.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex shapes - recommended is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth contact surface
- under conditions of no distance (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Heat warning
Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Dust explosion hazard
Powder produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Nickel coating and allergies
A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in skin redness. We strongly advise wear protective gloves.
Bodily injuries
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Safe operation
Handle with care. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
Magnets are brittle
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Warning for heart patients
Patients with a pacemaker should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the implant.
Keep away from electronics
Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Choking Hazard
Absolutely store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.
Threat to electronics
Do not bring magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
