(please help) A bar magnet is placed ona sheet of plain paper and the magnetic field lines of the bar magnet are located using a plotting compass, as shown in the diagram below.

The dots represent the positions of the pivot of the plotting compass as the compass is moved along a field line. The compass is at the point A.

1) Explain how you would complete the field line from point A to the South pole. You should say how you would use the Compass to help you mark the paper and how you would proceed from one dot to the next dot. You may draw on the diagram if you wish. (4)

Mark on the paper where the arrow is pointing. Move the compass so that the tail of the arrow is at the previously made mark, and make a new mark where the arrow is pointing. Repeat until the compass reaches the magnet's south pole.

Explanation:

A plotting compass is a small compass used for tracing magnetic fields. The compass needle looks like an arrow. To use a plotting compass, we place it near a magnet and mark where the arrow points. We then move the compass so that the tail of the arrow is at the mark we made. Then we make a new mark where the arrow is now pointing. We repeat this process until we've reached the magnet's south pole.
