Magnetic Domains

Mr. Anderson explains magnetic domains in ferromagnetic materials, using ferrofluids to visualize magnetic fields. He discusses how breaking a magnet results in smaller magnets due to internal magnetic domains. The video covers the alignment of these domains to create magnetization, the energy implications of magnetic domains, and natural and laboratory methods of magnetization.

Discuss the significance of having magnetic domains within a magnet.

How do external magnetic fields influence the alignment of magnetic domains?
