Dear student,                     
​Please find below the solution to the asked query  

3. Earth itself acts like a big magnet. It has some magnetic materials inside it, so when we suspend a magnet with a string, the magnet always stay in north – south direction and the north pole of the magnet is pointing towards the earth’s magnetic south  pole and south pole of the magnet is pointing towards the magnetic north pole of the earth.

In the method of single touching an artificial magnet (such as iron or steel) is made by rubbing a permanent magnet over it, in the same direction.
