A compass works in a magnetic field because it contains a small, lightweight magnet that is magnetized in a specific direction. This magnet aligns itself with the Earth's magnetic field, causing the needle to point towards the Earth's magnetic north pole.
Yes, a compass can be affected by other magnetic fields. Stronger magnetic fields, such as those produced by electronic devices, can cause the compass needle to deviate from its true north position. It is important to keep the compass away from any strong magnetic sources while using it for navigation.
If you put a compass near a magnet, the needle will be affected by the magnet's magnetic field and will move to align itself with the magnet's north and south poles. This can cause the compass to give an inaccurate reading of the Earth's magnetic field and may affect its ability to point towards true north.
A compass needle always points north because the Earth's magnetic field is aligned with the magnetic poles located near the geographic north and south poles. This causes the needle to align with the Earth's magnetic field and point towards the magnetic north pole.
Yes, a compass can work anywhere in the world as long as it is not affected by strong magnetic fields. However, the accuracy of the compass may vary depending on the location. This is because the Earth's magnetic field is not perfectly aligned with the geographic north and south poles, and the strength of the magnetic field can also vary in different locations.
