Question

8. Suppose you have a circular loop of copper wire through which a current flows clockwise. If this loop is
lying on a table, draw the pattern of magnetic field lines of this current carrying loop. State the rule you can
apply to determine the direction of the field lines in this case.​

Answer 1

If you are keeping a current-carrying straight conductor in your proper hand such that the thumb factors closer to the course of the current.

Explanation:

For the right side of the circular loop:

The direction of magnetic field lines will be as if they are emerging from the table outside the loop and while they will be going into the table inside the loop.

Similarly for the left side of the circular loop:

The direction of magnetic field lines inside the loop will also be going into the table while outside the loop they will be emerging from the table.
