Describe an activity with a neat diagram to show the magnetic field lines around a bar magnet.

(N/A) $1$. Place a sheet of white paper on a drawing board and fix it using adhesive tape.
$2$. Place a bar magnet in the center of the paper and mark its boundary.
$3$. Place a small compass needle near the north pole of the magnet. The south pole of the compass needle will point towards the north pole of the magnet.
$4$. Mark the position of the two ends of the compass needle with a pencil.
$5$. Move the compass to a new position such that its south pole occupies the position previously occupied by the north pole.
$6$. Repeat this process step by step until you reach the south pole of the magnet.
$7$. Join the marked points with a smooth curve. This curve represents a magnetic field line.
$8$. Repeat the process to draw several such lines around the magnet.
