The invisible force

You cannot smell, see, hear or feel magnetic force itself. So it seems quite magical to us when a metal object can be moved by a magnet through a glass plate as if by an invisible hand, or when we can stick a piece of paper to the refrigerator door with a small magnet.

Objects made of metal stick, float or are repelled by each other without us having a simple explanation of it.

But not only do many things we use in everyday life work with the help of magnetism, the Earth itself creates a magnetic field. So we are, on the one hand, surrounded by man-made magnetic objects, on the other hand, we live in a natural magnetic field produced by the Earth itself.
