demagnetise

demagnetise的音标为[ˌdeməˈɡnetaɪz]，意思是“使去磁”。

速记技巧：可以通过词根词缀快速记忆单词。在这个单词中，前缀de-表示“去掉、取消”，词根-magnetise/-magnetize表示“使...磁化”，后缀-ise/-ize是动词后缀。结合起来就是“去掉磁性”的意思。

Demagnetise这个词的词源可以追溯到拉丁语和希腊语，意为“去磁”。它的主要变化形式是名词形式demagnetism，表示一种现象，即物体失去磁性的现象。

相关单词：

1. Magnet - 磁铁，与demagnetise相反，表示具有磁性的物体。

2. Ferromagnet - 铁磁性物质，具有强烈磁性的物质。

3. Paramagnet - 顺磁性物质，在磁场中表现出微弱磁性的物质。

4. Antimagnet - 反磁体，与磁性相反的物质，通常指没有磁性的物质。

5. Antisperm - 反极性物质，与磁性相反的极性状态。

6. Depletion - 消耗，与demagnetise相关的动词形式，表示消耗或减弱磁性。

7. Demagnetization - 去磁，与demagnetise相关的名词和动词形式。

8. Magnetic Field - 磁场，与磁性相关的物理概念。

9. Magnetic Force - 磁力，物体间由于磁场产生的力。

10. Magnetic Susceptibility - 磁化率，表示物体对磁场敏感度的物理量。

以上这些单词都与demagnetise这个词相关，并且可以用来描述不同的磁性和物质状态。

英文小作文：

Demagnetization is an important process that is often necessary when dealing with magnetic materials and equipment. It ensures that the materials and equipment do not retain any magnetic properties and can be safely used in a variety of environments and applications.

When dealing with magnetic materials and equipment, it is important to understand the effects of magnetic fields and how they can affect the materials and equipment. Demagnetization is a process that can be used to remove these magnetic fields and ensure that the materials and equipment are safe for use in a variety of environments and applications.

Demagnetization can be achieved through various methods, including exposure to a strong magnetic field, heating the material or equipment, or using a magnetic field remover. Each method has its own advantages and disadvantages, and it is important to choose the method that is most suitable for the specific application and materials being used.

In conclusion, demagnetization is an essential process in dealing with magnetic materials and equipment, ensuring that they are safe for use in a variety of environments and applications. Understanding the effects of magnetic fields and how to remove them is crucial for ensuring safe and effective use of magnetic materials and equipment.
