Question

which statement correctly describes magnetic field lines? a. they are parallel with one another. b. they show the direction a south pole will point. c. they join north pole to north pole. d. they form loops.

Explanation:

• Magnetic field lines are not parallel. In non - uniform fields (like around a bar magnet), they curve.
• Magnetic field lines show the direction a north pole would point, not a south pole.
• Magnetic field lines go from the north pole to the south pole outside the magnet and from south to north inside, forming closed loops. They do not join north - pole to north - pole.

Answer:

D. They form loops.
