Desktop Scanning Electron Microscopy—Sampling Method for Magnetic Materials

Desktop Scanning Electron Microscopy—Sampling Method for Magnetic Materials In this issue, we will talk about the method of using a desktop scanning electron microscope to observe the sample preparation method of magnetic materials. Generally, demagnetization is required before analysis. The main reasons are as follows: 1. Generally, the lens and scanning coil of a desktop [...]

  • Scientists Find That Some Magnetic Materials Freeze When Heated

Scientists Find That Some Magnetic Materials Freeze When Heated

Scientists Find That Some Magnetic Materials Freeze When Heated Physicists have found that some magnetic materials freeze when the temperature rises above a certain level. Usually, freezing occurs only when an object is cooled, not when it is heated. So this leaves physicists scratching their heads and bewildering. Heating but freezing? Alexander Khajetoorians, a physicist [...]

  • Hast Aging Test Chamber for Magnetic Materials

Hast Aging Test Chamber for Magnetic Materials

Hast Aging Test Chamber for Magnetic Materials Magnetic material hast aging test box is also called high-voltage accelerated aging tester. The purpose of the test is to improve environmental stress (such as: temperature) and working stress (voltage, load, etc. applied to the product), speed up the test process, and shorten the product or system. life [...]

  • Development of Zinc Oxide and Magnetic Materials

Development of Zinc Oxide and Magnetic Materials

Development of Zinc Oxide and Magnetic Materials In zinc-manganese ferrite cores, zinc oxide is the main raw material. In the production of medium and high-grade ferromagnetic materials, the high-end zinc oxide of the zinc oxide varistor grade produced by the indirect method must be used. The development of permanent magnet materials has promoted the scientific [...]

  • Standards and Requirements for Using NdFeB Magnets

Standards and Requirements for Using NdFeB Magnets

Standards and Requirements for Using NdFeB Magnets Neodymium iron boron magnets are particularly strong in magnetism. The first thing to do is to prevent hands or other parts of the body from being clamped by the magnets. More attention should be paid to safety for large-scale strong magnetism. Do not place strong magnets near electronic [...]

  • Concentration Problem of Powerful Strong Magnets

Concentration Problem of Powerful Strong Magnets

Concentration Problem of Powerful Strong Magnets One of the daily tasks in the overall planning of the equivalent circuit of a strong magnet is to drive the magnetic flux density of the magnetic air gap as far as possible. The analogy of the power circuit to the current intensity driving is simple, just modify the [...]

  • Motor Arc Segment Magnet Drawing Reference

Motor Arc Segment Magnet Drawing Reference

Motor Arc Segment Magnet Drawing Reference In the case where there is no or inconvenient to provide arc magnet samples, drawings are also very important for magnet manufacturers, which is related to the accuracy of arc segmented magnets, so custom or need motor arc magnet magnetic tiles (Ferrite arc magnet NdFeB arc magnet) When taking [...]

  • Neodymium Radial Magnetized Ring Magnets Application Schematic

Neodymium Radial Magnetized Ring Magnets Application Schematic

Neodymium Radial Magnetized Ring Magnets Application Schematic Regarding the radial magnetization of magnets, many people do not know much about the contact with them, so they do not have a strong concept of radial magnetization. Radial magnetic ring magnetization is actually diametrical magnetization, and their strong magnetic surface is on the side of the ring. [...]

  • How does Encoder Magnetic Ring See the Number of Poles

How does Encoder Magnetic Ring See the Number of Poles?

How does Encoder Magnetic Ring See the Number of Poles? The magnetic ring on the encoder is mostly made of ferrite, such as sintered ferrite, injection molded ferrite, and the number of magnetized poles is generally more. How to see the number of poles for the encoder magnetic ring? Some netizens have made difficulties. The [...]

  • Function and Use of the Magnetic Pole Sheet

Function and Use of the Magnetic Pole Sheet

Function and Use of the Magnetic Pole Sheet We can't see the magnetization method of magnet products with the naked eye. We don't know whether it is ordinary magnetization or multipole magnetization. We can only check it by using the magnetic pole observation piece, and judge the magnetization method and the number of magnetization poles [...]

  • How Much is a Sample Neodymium Arc Magnet

How Much is a Sample Neodymium Arc Magnet?

How Much is a Sample Neodymium Arc Magnet? Sample Neodymium Arc Magnet refers to testing before subsequent mass production, small-scale trial production, mainly for engineers to test and analyze whether the motor is running normally. Since the motor usually uses multi-piece tile-type magnets, for cost considerations, many purchasers will ask you how much does a [...]
