A child staying in a coastal region test 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 ex¬plain the reason?

Help plz..!

Answer 1

$\huge\tt\pink{Answer}$

• The seawater contains a huge amount of salts in comparison to drinking water, hence the seawater is a better conductor of electricity and it produces a stronger magnetic field in the wire and hence deflects the compass needle more.

Answer 2

Answer:

Sea water contains more dissolved salts than the drinking water. Therefore, it is more conducting than the drinking water. Due to this reason, the compass needle deflects more in seawater than in the drinking water.
