6.5 understand that magnetism is induced in some materials when they are placed in a magnetic field
magnetism can be induced in some non-magnetic materials when they are placed in a magnetic field (materials containing iron, nickel or cobalt)
this is because the magnetic field encourages the electron line up and form poles inside the material
in magnetically soft materials, the magnetism will disappear after the magnet is moved away (iron is a magnetically soft material)
