A compass behaves as it does because each needle acts as a(n) ____
 A Magnet B Guide C Either A or B D None of the above
Explanation:

Detailed explanation-1: -Magnetic compass has a rod and this rod is made of a magnetized ore of iron. . The compass needle behaves as a bar magnet.It has a north pole and south pole .

Detailed explanation-2: -When you use a compass to see which way is north, south, east, and west, you are really using a magnet. The little moving pointer in a compass is actually a small magnet! The needle lines up and points in a certain direction because Earth itself has magnetism and acts like a magnet too!

Detailed explanation-3: -The line of magnetic field makes a close loop but it starts from north pole to south pole and magnetic needle follows its direction as it is made of iron or steel and magnetized by lodestone. So when we place it in a magnetic field it assures a position which follows a line of magnetic field.

Detailed explanation-4: -This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earthâ€™s magnetic field direction and points north-south.

Detailed explanation-5: -When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
