GEOLOGY

Detailed explanation-1: -Compass needles are designed to align with Earth’s magnetic field, with the north end of the needle pointing to the magnetic North Pole and the opposite end of the needle pointing to the magnetic South Pole.

Detailed explanation-2: -Since Earth is a magnet, a compass will normally line up with Earth’s magnetic field. Because opposite magnetic poles attract, the magnetic north pole of the compass points toward the magnetic south pole of the Earth. (The magnetic south pole of the Earth is located in northern Canada-that is not a misprint.

Detailed explanation-3: -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.

Detailed explanation-4: -From the south magnetic pole to the north magnetic pole, this force has an effect on all magnetized objects, such as the needle of a compass. Under the effect of Earth’s magnetic field, the needle always points toward the north magnetic pole.

Detailed explanation-5: -Earth’s south magnetic pole is near Earth’s geographic north. Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a compass points toward north because that’s where Earth’s south magnetic pole is located and they attract.
