When a magnet is brought close to a ferromagnetic material such as iron.........

some of the "magnetic domains" in the material change so that the material

becomes a magnet. ..............

This process is called magnetic induction. ....

When the magnet is removed......

most of the domains change back to the way they were

before, so that the material is no longer a magnet........

  Materials,,,which act this way are called nonretentive or magnetically soft magnetically soft

materials.....
