霍尔元件可大致分为两类:线性霍尔和开关霍尔.人教版高中物理新教材选修3-1和选修3-2上涉及的主要是霍尔元件的线性特征.而实际上,随着电子电路的数字化的倾向,开关霍尔的应用远远大于线性霍尔,在近年各地高考及模拟中也多次出现和霍尔应用相关的试题,但广大教师和学生对真实霍尔元件却了解甚少,影响对题意的理解.本文就生产生活中常见的开关霍尔元件的电气特性及其应用作一简单介绍,感兴趣者可以
Hall elements can be broadly divided into two categories: linear Hall and switch Hall.Philips Education High School Physics New Textbook elective 3-1 and elective 3-2 are mainly involved in the linear characteristics of the Hall element.However, With the digital tendency of electronic circuits, the application of switch Hall is far more than that of Linear Hall. In recent years, entrance examination and simulation have appeared many times and Hall applications related questions, but the majority of teachers and students on the real Hall element But little understood, affecting the understanding of the subject.This article on the life of the common switch Hall element electrical properties and their applications for a brief introduction, interested can
