- a north pole attracts a south rod a south pole draws a north pole.
While the north rod out of a-compass facts everything towards the geographical north, the earth have to have a charismatic southern area rod close to the geographic North Rod, because shown for the Profile dos. (This new magnetized community lines found from inside the Profile 2 might possibly be discussed in Subsection 2.step three ).
Due to the fact a-compass needle goes into a specific positioning whenever not any other magnets was near, the fresh implication is the fact that World in itself need magnetized features
Note: The world renders an entire revolution every 24 h on the an enthusiastic axis through the geographic posts, which can be acknowledged by watching the latest visible action out of superstars. g. the newest pole superstar) seems fixed, or any other celebrities appear to relocate sectors to that time. This new Earths magnetized poles was next to, whether or not nearly coincident that have, the geographical poles.
