1.Magnetic Flux Density (Gauss or Tesla):
The magnetic flux density of block magnets is a fundamental measure of their strength. Gauss or Tesla are the units used to quantify this property, representing the density of magnetic field lines within a given space. For instance, a high Gauss rating indicates a strong magnetic field. In applications like magnetic resonance imaging (MRI) machines, block magnets with high magnetic flux density are crucial for generating the intense magnetic fields needed for medical imaging.
2.Magnetic Field Strength (Oersted):
Magnetic field strength is a measure of the force exerted by a magnetic field within a material. Expressed in Oersted, it is vital for understanding how well a block magnet can magnetize other materials. This is particularly relevant in the design of magnetic circuits, where achieving a desired field strength is critical. For instance, in electromagnetic devices like solenoids, block magnets contribute to the overall magnetic field strength, influencing the device's performance.
3.Residual Induction (Br):
Residual induction, denoted as Br, signifies the maximum magnetization a material can retain. In permanent magnets like block magnets, a high Br value indicates a strong magnetic field even after the removal of an external magnetic field. In electric motor applications, block magnets with high residual induction are essential for maintaining strong magnetic fields within the motor's rotor, ensuring efficient operation.
Coercivity measures a material's resistance to demagnetization. In applications subject to temperature variations, a block magnet with high coercivity is crucial for maintaining stability. In magnetic sensors used in automotive applications, for instance, block magnets with high coercivity ensure reliable and consistent performance under varying temperature conditions.
5.Energy Product (BHmax):
The energy product, denoted as BHmax, is a key parameter representing the maximum magnetic energy a material can store. In high-performance applications such as magnetic resonance imaging (MRI) or magnetic levitation systems, block magnets with a high energy product are preferred for their ability to deliver strong magnetic forces efficiently.
6.Magnetic Pull Force:
Magnetic pull force is a practical measure of a magnet's strength in real-world scenarios. In applications like magnetic clamping systems used in manufacturing, block magnets with a high pull force ensure a secure grip on ferrous materials, enhancing the efficiency and safety of the clamping process. This practical metric is often crucial for applications where physical contact between the magnet and other materials is necessary.
Gaussmeters, magnetometers, and Hall effect sensors are essential instruments for measuring the magnetic strength of block magnets. Gaussmeters, for example, provide quantitative data on the magnetic flux density, aiding in the precise characterization of the magnet's strength. In research and development laboratories, these instruments are indispensable for ensuring the quality and consistency of block magnets in various applications.
The magnet is surrounded by six equal square faces, and the angle between any two adjacent faces of the magnet is a right angle.
This magnet is made of neodymium and is 21 times stronger than a ceramic magnet of the same size.
They are magnetized by thickness. They are composed of neodymium iron boron magnetic material, and are plated with nickel, copper and nickel, and have a shiny, corrosion-resistant surface.
