Other proposals
Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain attractive force for nearly 10 years – the drop is just ~1% (based on simulations),
- They are resistant to demagnetization induced by external disturbances,
- Thanks to the shiny finish, the coating of nickel, gold-plated, or silver gives an clean appearance,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of exact forming and adjusting to individual applications,
- Universal use in modern industrial fields – they are commonly used in mass storage devices, motor assemblies, precision medical tools, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets demagnetize 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
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness reaches at least 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Keep away from electronics
Remember: rare earth magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, device, and GPS.
No play value
Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
Bodily injuries
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Do not drill into magnets
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Respect the power
Use magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their force.
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Thermal limits
Keep cool. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Protect data
Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Warning for heart patients
Individuals with a pacemaker must keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Magnet fragility
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
