Discussion
Given below are two statements :
Statement I : Magnetite is a natural magnet.
Statement II : A freely suspended magnet always aligns in N-S direction.
In the light of the above statements, choose the most appropriate answer from the options given below :
Answer: A
Both Statement I and Statement II are correct.
Magnetite (Fe3O4) is the iron ore that occurs naturally magnetised as lodestone. It was the first natural magnet known and was used in early compasses.
A freely suspended bar magnet turns to lie along the Earth's magnetic field, with its north pole pointing roughly towards geographic north. That is the basis of the magnetic compass. Strictly it points to magnetic north, which differs slightly from true north, but the textbook statement is accepted.
