Science (086) — AI-generated practice question

A magnetic field line diagram conveys both properties as follows:

Direction: The arrows marked on field lines show the direction of the magnetic field at any point. By convention, field lines emerge from the north pole and merge at the south pole of a magnet (and run from south to north inside the magnet).

Magnitude: The relative strength (magnitude) of the magnetic field is shown by the degree of closeness (crowding) of the field lines. Where field lines are closer together, the magnetic field is stronger; where they are farther apart, the field is weaker.

• The examiner expects two clearly separated points — one for direction, one for magnitude — since the question explicitly asks about "EACH of these two properties."
• The key phrases to use: arrows on field lines (direction) and degree of closeness/crowding (magnitude/strength).
• Do not confuse "magnitude" with "direction" — keep them distinct in your answer.
• These exact statements appear in Section 12.1 of the textbook and are frequently tested in board exams.
