Question

Part A. Shown below are a side-view diagram and a top-view (cross-sectional view) diagram of a current carrying wire. A point near the wire (Point A) is shown in both diagrams. Side view Top view (cross-sectional view) of current-carrying wire of current-carrying wire i out of page O c j into page 8 COA. k zero Question 1. what is the direction of the magnetic field at point A in the side-view diagram and in the top-view diagram? Select your answer from the figure at right above j k (Zero) Direction of magnetic field in side-view diagram Direction of magnetic field in top-view diagram

Explanation / Answer

Question 1:

In the side view diagram, electric field is going in direction j- going into the page.

In the top view diagram, the electric field is going in direction a.

Question 2: We have used the right hand rule to obtain the directions. According to the right hand rule, if we point our thumb in the direction of flow of current then the curl of fingers gives the direction of the electric field generated by it.
