demagnetize

demagnetize的音标是[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-magnetize表示“使磁化”，后缀-ize表示使…化。因此，可以联想到这个单词的含义是“使去磁”。

Demagnetize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“去磁现象”或“大众影响”。

相关单词：

1. Magnet - 磁铁，这个词源自拉丁语magnetis，意为“磁性的”。

2. Magnetism - 磁力，这个词源自希腊语magnetikos，意为“磁性的”。

3. Antimagnet - 抗磁性物质，这个词由ant-（反）和magnet（磁）组成，表示与磁性相反的性质。

4. Demagnetization - 去磁过程，这个词由de-（否定）和demagnetize（去磁）组成。

5. Magneto - 磁性相关的词缀，可以构成如电磁、磁化等词汇。

去磁这个词在英语中常常用于描述去除物体或现象的磁性属性，这个词的使用也反映了人们对磁性的理解和应用的历史。在现代科学和工程中，人们通过各种方法和技术来研究、控制和利用磁性。

英文小作文：

Demagnetization is an important process in many applications, such as magnetic recording and data storage devices. When a magnetic material is exposed to a strong magnetic field, it will be magnetized, which can be reversed by exposing it to a weaker magnetic field or by heating it up to a certain temperature. However, if the magnetic material is exposed to a strong magnetic field for a long time, it will be demagnetized, losing its magnetization completely. This process can be reversed by exposing it to a weaker magnetic field or by cooling it down to a lower temperature. Therefore, demagnetization is an essential process in many applications, and it is crucial to ensure that the magnetic material is properly demagnetized before it is used in any application.
