Solution
The correct option is B Both 1 and 2
The lines obtained are magnetic field lines. They have a particular magnitude and direction at every point. Closer lines indicate a stronger magnetic field. However, these lines only come into existence when we join the points obtained by marking the direction which the compass points in. If we take away the paper, there does not exist any line. Hence, they are imaginary lines.
