The wire hanging between the grips of the U-magnet is connected to the power source 2V, 2...3A. When the electric current is switched on, the wire starts to move to one side or the other between the U-magnet's grips depending on the polarity of the supply voltage.

Lessons about magnets Children learn about the properties of magnets. Half of the bar magnets in the kit do not have pole marks so that the children learn to determine north and south poles for themselves. Lessons about the magnetic compass Experiments with suspended or floating magnets lead to an understanding of how compasses work. Children also learn to assemble their own compasses and to use them properly.
