Advantages as well as disadvantages of rare earth magnets.
Advantages
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- They retain their magnetic properties even under close interference source,
- A magnet with a metallic nickel surface looks better,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Due to the potential of flexible forming and customization to specialized projects, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Fundamental importance in modern technologies – they serve a role in mass storage devices, electric drive systems, advanced medical instruments, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can 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
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness reaches at least 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- under axial force vector (90-degree angle)
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin steel does not accept the full field, causing part of the flux to be lost into the air.
- Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Allergy Warning
Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Extended handling might lead to a rash. It is best to wear safety gloves.
Keep away from electronics
Note: neodymium magnets produce a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Electronic devices
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Fragile material
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Medical implants
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
This is not a toy
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
Crushing risk
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Conscious usage
Handle magnets consciously. Their immense force can shock even professionals. Be vigilant and do not underestimate their force.
Permanent damage
Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
