Materiales magnéticos y no magnéticos

Principle

The students should understand that objects, which are made of iron − or, at least, contain iron − are attracted by a magnet. They should further become aware that both poles of a magnet are identical in their effects on iron ...

Polos magnéticos y su distinción

Principle

The pupils should understand

  • that that it is at the two ends of a bar magnet, the magnetic poles, that the strongest forces appear.
  • why the two ends of a magnet are called the north and the south poles.
  • how one can identify the two poles.
  • which forces appear between ...

Atracción magnética (acción remota)

Principle

The pupils learn that

  • magnetic forces also act when a magnet and an iron object are not in contact.
  • the magnetic force increases with decreasing distance.
  • the magnetic force depends on the size of the attracted object.
  • the magnetic force can pass through materials which ...

Descomposición de imanes (imanes elementales)

Principle

The students should learn that, on dividing a magnet into two pieces, magnets having north and south poles are always produced. It is not possible to produce a magnet with only one pole.

Benefits

Quick and easy experiment for qualitatively understanding of magnetic ...

Composición de imanes

Principle

The pupils should observe and be able to explain that magnets lying next to each other produce a stronger effect than an identical, single magnet when the two magnets are so positioned that identical poles face one another; when the magnets are arranged so that opposite poles face ...
