Question

question 12 of 20 suppose you were to make a three - dimensional model of magnetic force using magnetic field lines and a magnet. which two characteristics might your model have? a. arrows on the field lines point from the magnets north pole to its south pole. b. the field lines near the magnet are far apart. c. the field lines exist only at the top and the bottom of the magnet. d. the field lines do not cross paths as they go from one pole of the magnet to the other.

Explanation:

Magnetic field lines are defined to point from the north - pole to the south - pole of a magnet outside the magnet. Also, magnetic field lines never cross each other as the direction of the magnetic field at a point is unique. Field lines near a magnet are close together indicating a stronger field, and they exist in 3 - D space around the magnet, not just at the top and bottom.

Answer:

A. Arrows on the field lines point from the magnet's north pole to its south pole.
D. The field lines do not cross paths as they go from one pole of the magnet to the other.
