Chapter 20, Problem 2Q

To determine

TheEarth’s north pole is south pole of the magnetand an experiment on how to indicate north and south pole.

Answer to Problem 2Q

Solution:

Yes, the Earth north pole is a south pole and the experiment to indicate is the using Compass.

Explanation of Solution

Introduction:

All magnets have a north seeking pole and is colored red in the compass or magnet. The opposite pole is the south pole. And the two opposite poles of a magnet always attract each other and the like poles of a magnetic always repel each other.

Therefore, when the red end is pointing in the north direction, it is attracted by the south pole of another magnet colored in blue.

Therefore, while assuming Earth as a big magnet, the south pole of magnet is underneath the north pole of Earth.

The geographic North pole of the Earth is the South pole of the Earth’s magnetic field as shown below:

The experiment used to identify Magnetic north pole is using a compass.

Experiment: Take a magnetic compass and place it close to the magnet and have your eyes on the compass needle to see in which direction they point.

The point that normally points to the north pole of Earth should point to one end of the magnet., that is the south pole, because, the Earth’s geographic North pole acts like the south pole to a magnet and the opposite poles of two magnets attract. Each other.
