Chapter 36, Problem 16A

How do the concepts of force, field, and current relate to a galvanometer?

To determine

To explain: The relation of concept of force, field, and the current a galvanometer

Explanation of Solution

Introduction:

The galvanometer is a device used for measuring the current. It is used to detect the direction of the flow of current.

According to the principle of the galvanometer, the current carrying conductor is kept between the magnetic field, hence experiences a force. Mathematically, the current, field and force are related as:

  $F=NBIl$

Conclusion:

Hence, a galvanometer is based on the principle that the current carrying coil kept between the magnetic field experiences a force.
