The magnet is located in the blue tube inside the bottom tank where the water flows through to the tap. Water molecules are dipolar and tend to attract each other. Magnets affect the bonding angle between the hydrogen and oxygen atoms in the water molecule. This in turn reduces the molecule cluster groups to become smaller and this is suggested to increase absorption. Agglomeration is defined as the gathering of mass and as the magnet reduces this mass into smaller clusters it decreases agglomeration.
