PDF The Usborne Book of Batteries & Magnets (How to Make) Free Books - Video DailymotionBy Steve Bush 7th March On the radio yesterday morning were some interviews with folk that were in at the start of Ladybird Books.

Water is dimagnetic, which means that it exerts a weak magnetic field, and repels other magnetic fields. If a magnet is suspended over water, the water's dimagnetism will repel the magnet. This weakens the magnet's effect on other objects.

However, salt water conducts electricity better than non-salt water, so magnets placed near it can cause significant turbulence in the water.
