Earth’s magnetic field and a bar magnet both attract particles to the same locations. Where are they?
A
the middle
B
all around the outside
C
the North and South poles
D
first to the middle, then to the ends
Explanation: 

Detailed explanation-1: -The south pole of the earth’s magnet is in the geographical north. Similarly, the north pole of the earth’s magnet is in the geographical south. This is because Earth itself is a giant magnet and all the magnetic compass is attracted by the magnetic field of the earth.

Detailed explanation-2: -Earth acts as a bar magnet. Like any other magnet it also forms magnetic field lines around it. These magnetic line moves from the north pole to the o south pole. These magnetic field lines are generally curved lines stretched like rubber bands.

Detailed explanation-3: -Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.

Detailed explanation-4: -The north-seeking pole of a magnet was defined to have the north designation, according to their use in early compasses. Because opposite poles attract, this means that as a physical magnet, the magnetic north pole of the earth is actually on the southern hemisphere.
