Answer 2

Answer:

The earth has a magnetic field that runs approximately north and south.

The needle is magnetic, and as such, it aligns itself with the magnetic field of the Earth. On magnets, north poles attract south poles, and vice versa.

The magnetic needle lines up with Earth’s magnetic core, so it points north.

And that's how a compass works!
