Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the drop is just ~1% (based on simulations),
- Magnets perfectly resist against loss of magnetization caused by foreign field sources,
- Thanks to the shiny finish, the surface of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Magnetic induction on the top side of the magnet remains strong,
- 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...
- Thanks to flexibility in forming and the capacity to modify to unusual requirements,
- Versatile presence in modern industrial fields – they find application in magnetic memories, drive modules, medical devices, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a cross-section no less than 10 mm
- characterized by smoothness
- with zero gap (no paint)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Plate thickness – too thin steel does not accept the full field, causing part of the power to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Medical interference
Patients with a pacemaker should maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Flammability
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Protective goggles
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Immense force
Be careful. Neodymium magnets act from a distance and connect with huge force, often faster than you can move away.
This is not a toy
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Cards and drives
Do not bring magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop handling magnets and use protective gear.
Impact on smartphones
A powerful magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Thermal limits
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Crushing risk
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
