"Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. " -- Keith Cooley, astronomer, 2002
Looks like water is also magnetic.
Physics World: Magnetic effects seen in water.
Physicists in Japan have discovered that the melting point of water increases slightly in a strong magnetic field. ...
Recently, it was discovered that the near infrared spectrum and refractive index of water can be affected by a strong magnetic field. Some researchers have suggested that the magnetic field somehow strengthens hydrogen bonds, but the exact mechanism behind these results remains a mystery.
