Diametrical: A special direction of magnetisation

In magnet technology, the term diametrical describes a specific direction of magnetisation in which the magnetic poles are arranged along the diameter of a cylindrical magnet. In contrast to axial magnetisation, in which the poles are located at both ends of a cylinder, in diametral magnetisation the poles are distributed laterally on the surface of the cylinder.

What does diametral magnetisation mean?

In diametral magnetisation, the magnetic field runs across the diameter of a magnet. A typical example is a cylindrical magnet with the north pole on one side of the cylinder and the south pole on the opposite side. This type of magnetisation is used specifically to generate certain rotational movements or lateral attractions.

Properties of diametrically magnetised magnets

• Direction of magnetisation: The magnetic poles are located along the diameter of the magnet.
• Magnetic field orientation: The magnetic field is orientated laterally, which is important for specific applications.
• Shape: Diametrically magnetised magnets are often cylindrical or disc-shaped.

Examples of diametrically magnetised magnets

• Rotational applications: In rotating systems, diametrical magnetisation is used to generate uniform rotational movements.
• Sensor technology: Magnetic field sensors use diametrically magnetised magnets to measure precise position data.
• Speakers: Some speaker designs use diametrically magnetised magnets for optimal sound transmission.

Applications of diametrically magnetised magnets

• Electric motors: In electric motors, diametrical magnetisation provides the necessary rotation.
• Measuring devices: This type of magnetisation is often used in torque or angle measuring devices.
• Medical devices: Some imaging procedures use diametrically magnetised magnets for precise field control.

Interesting facts about diametrically magnetised magnets

Did you know that diametrically magnetised magnets are able to generate rotary movements in a way that is not possible with axially magnetised magnets? This property is utilised in modern precision motors and sensors to achieve maximum efficiency.
