The magnetic compass operates on the principle that _____

The magnetic compass operates on the principle that unlike magnetic poles attract. In the context of a magnetic compass, the north end of the compass needle (which is magnetized) is attracted to the Earth's magnetic north pole—this is located not at the geographic north pole but rather some distance away due to the Earth's magnetic field. Therefore, the north-seeking end of the compass needle points toward the magnetic north, indicating direction.

The principle of attraction between unlike poles is fundamental to how magnetism works in general and is essential for the compass to accurately indicate direction. The compass needle's alignment with the Earth's magnetic field allows mariners and travelers to find their bearings, making this understanding critical for navigation.
