The use of sintered NdFeb permanent magnet material (2)

2023-02-16

Sintered NdFeb Permanent Magnet material, because of its excellent magnetic properties and cost-effective, is widely used in a variety of fields, today take you to understand the use of sintered NdFeb permanent magnet material.

1.Lock the door

Neodymium Magnets are used in public, commercial and residential buildings to create magnetic door locks. A countersunk or can-shaped magnet embedded in the door surface is used to attract another wall-mounted magnet or steel plate. The strong neodymium magnets easily support the weight of the door, and the leverage provided by the door means the magnets can be easily detached.

2. Motors and generators
Electric motors rely on a combination of electromagnets and permanent magnets (usually neodymium magnets) to convert electrical energy into mechanical energy. A generator, by contrast, converts mechanical energy into electricity by moving a conductor in a magnetic field.

Step 3: Jewelry
Small magnets are used to make jewelry and to make jewelry buckles. Countersunk neodymium magnets have opposite poles on the countersunk surface, providing a firm fixation, and since neodymium is the strongest Magnetic Material in the world, a magnet as small as 5 mm in diameter is effective.

4. Bearing
Magnetic bearings use the concept of magnetic levitation to support moving parts without physical contact. They are used to achieve relative motion with very low friction and no mechanical wear even at incredible speeds. Bearings called passive magnetic bearings use permanent magnets, such as neodymium magnets, while active magnetic bearings use electromagnets.

5.MRI scanner
The MRI scanner generates a large magnetic field that aligns protons in the body in the direction of the field. Radio-frequency waves are then directed at the body to produce a detailed image of the interior. Many of the "open" MRI machines used in hospitals use large neodymium magnets, and they do help save lives.

6. Magnetic therapy
Although not clinically proven, many people believe that magnets can relieve pain by subjecting certain parts of the body to the magnetic field created by permanent magnets. Neodymium magnets are a popular choice for magnetic therapy believers because of their strength.
