Chapter 29: Q. 5 (page 829)

What is the current direction in the wire of FIGURE Q29.5? Explain.

Short Answer

Expert verified

The current direction will be downward.

Step by step solution

01

Given information

We have given,

a current carrying wire producing the magnetic field around it.

We have to find the direction of current in wire.

02

Simplify

From the diagram, here the cross sign indicates the magnetic field inward the paper and the dot sign indicts the magnetic field outward the paper.

Now by using right hand thumb rule curl the field in the direction of magnetic field and the thumb will show the direction of current which is downward.
