Chapter 29: Q. 11 (page 829)

The south pole of a bar magnet is brought toward the current loop of FIGURE Q29.11. Does the bar magnet attract, repel, or have no effect on the loop? Explain.

Short Answer

Expert verified

The magnet will repel the loop.

Step by step solution

01

Given information

We have given,

The south pole of a bar magnet is brought toward the current loop.

We have to find the effect of magnet on loop.

02

Simplify

We know the current carrying wire is producing itself a magnetic field.

From the figure, By apply right hand thumb rule on the current loop than we will find out the magnetic field such that the south pole will be right side of the figure as shown.

Since we brought the south pole toward the south pole of the wire then it will start repel.
