प्रश्न
Since every iron atom is a tiny magnet, why are not all iron bar magnets?
उत्तर
Each molecule of a magnetic substance is an independent magnet. But in an unmagnetised iron piece, molecular/ atoms (tiny magnets) are not arranged in any order and hence they neturalise the magnetic forces of each other As a result, any unmagnetised iron piece can not behave as a magnet.
