Question

State whether true or false:

According to Ewing's molecular theory, every molecule of a given substance is a magnet by itself.

• A. True
• B. False

Answer 1

The correct option is A True

If we break a magnet into two parts each part become a magnet with a north pole at one end and a south pole at the other end. If we break it further, we observe the same behavior. This will continue even if we break the magnet to its molecular level.
Each molecule of a magnetic substance is an independent magnet irrespective of whether the substance is magnetized or not. These tiny magnets are called molecular magnets.
Webers theory is based on the fact that all atoms have magnetic properties due to the spinning action of the atoms electrons. Magnetic materials and composed of groups of tiny magnets at a molecular level around the atoms, and a magnetised material will have most of its tiny magnets lined up in one direction only to produce a north pole in one direction and a south pole in the other direction.In a non-magnetized state, the molecular magnets are in different orientation. Therefore the net magnetic effect is zero.
Hence, every molecule of a given substance is a magnet by itself.
