What is a magnetic domain?

Back

A magnetic domain is a region within a magnetic material where the magnetic moments of atoms are aligned in the same direction.

How do compasses work?

Back

Compasses work by aligning a small magnet (the needle) with the Earth's magnetic field, pointing towards magnetic north.
