Advantages as well as disadvantages of rare earth magnets.
Pros
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under strong external field,
- By applying a shiny layer of nickel, the element gains an professional look,
- Magnetic induction on the working part of the magnet is impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom modeling and modifying to precise needs,
- Fundamental importance in innovative solutions – they serve a role in computer drives, brushless drives, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease 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 durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- under axial force vector (90-degree angle)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Threat to navigation
Remember: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Electronic devices
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Eye protection
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Crushing force
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact or choose versions in plastic housing.
Machining danger
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Respect the power
Handle with care. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
Danger to pacemakers
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
No play value
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store away from children and animals.
