摘要: 本文扼要地介紹了測(cè)量磁場(chǎng)的各種電測(cè)方法并作了比較。詳細(xì)論述了測(cè)量偏轉(zhuǎn)線圈磁場(chǎng)的原理及方法。提出了三探針的測(cè)場(chǎng)機(jī)構(gòu)及切實(shí)可行的測(cè)量裝置。測(cè)出了電視偏轉(zhuǎn)線圈的磁場(chǎng)參數(shù)曲線H0(z)、H2(z)及H4(z)。

Abstract: In this paper some methods for measuring magnetic fields are described coneisely and a comparison between these methods is made. The general theory and experiment-al method for measuring the TV deflecting magnetic field are given in detail. A practical measuring set up is presented. The curves of the magnetic field parameters H0(z), H2(z) and H4(z) are shown. -
