The most powerful magnetic product ever, rare earth magnet. The most commonly used rare earth magnet is Neodyum. The alloy of the magnet contains boron and iron. The rare earth magnet with many advantages is preferred in most industries.
Properties of Neodymium Magnets
- They have a maximum magnetic energy field.
- It has maximum coercive forces.
- They have maximum residual magnetism.
- Only 1% of magnetic energy is lost for 10 years.
- It has high corrosion resistance.
- They can be produced in any way (disc, ring, segment, rod, etc.).
The need for magnets in different shapes and sizes occurs in the industrial world. Neodymium magnets can be produced in desired shapes and sizes according to the need.
- In all clamps from household tool holders to magnetic clamps of heavy equipment,
- Cleaning, separation and filtering systems,
- Metal detectors,
- Hard disk drives and erase heads,
- Acoustic equipment,
- Turbines and generators,
- Compression, lifting, stepping and electric motors,
- They are used in medical materials.
Apart from the areas mentioned above, Neodymium magnets are also used in toys. It is possible to see the use of Neodymium magnets in many parts of daily life.
Neodymium magnets must have an alpha numeric name that describes the main performance characteristics of the product. The letter indicates the temperature range at which the magnet retains its properties; the number represents magnetic energy or pulling force.
Magnet Classes According to Operating Temperatures
- For magnets working up to N, 80 ° C,
- M for magnets working up to 100 ° C,
- H for magnets working up to 120 ° C,
- SH for magnets working up to 150 ° C,
- UH for magnets working up to 180 ° C,
- EH is used for magnets working up to 200 ° C. Subzero temperatures do not affect the working principle of Neodymium magnets.
When deciding on the Neodymium magnet you will use, it should be remembered that the separation force depends not only on the physical properties, but also on the dimensions of the product. For example, a 25 × 20 magnet is easier to remove than a 40 × 5 magnet because it has a smaller contact area with the metal. However, due to the longer magnetic lines, the gripping force is much higher.
When deciding on the right Neodymium magnet you need, seeking help from the manufacturer will be the healthiest choice.
