Question

What is meant by the term terrestrial magnetism?

Answer 1

Terrestrial magnetism:

1. The branch of physics which deals the study of the earth's magnetic field is called terrestrial magnetism.
2. Poles of a bar magnet are located at their two ends.
3. The magnetic pole is the region at each end of a magnet where the external magnetic field is the strongest.
4. When a bar magnet is suspended in the Earth’s magnetic field orients itself in a north-south direction. The north-seeking pole of such magnet, or any similar pole, is called a north magnetic pole.
5. The north pole of the earth's magnet is in the geographical south because it attracts the south pole of the suspended magnet.
