A child staying in a coastal region tests the drinking water and also the seawater with his tester. He finds that the compass needle deflects more in the case of seawater. Can you explain the reason?
Sea water contains more dissolved salts than the drinking water because drinking water is made pure by many methods. Therefore, seawater is more conducting than normal drinking water. Because of this reason, the compass needle deflects more in seawater than in the drinking water.
