Chapter 19: Problem 4

Two identical bar magnets lie next to one another on a table. Sketch the magnetic field lines if the north poles are at opposite ends.

Short Answer

Expert verified
Short Answer: The magnetic field lines of two identical bar magnets with their north poles at opposite ends will form an interacting pattern. At the center, where the south pole of one magnet is next to the north pole of the other, the field lines will combine and form loops connecting the north and south poles of both magnets. At the outer sides, where the north poles are at opposite ends, the field lines will repel each other and form loops that extend outwards before returning to their corresponding south poles. The field lines should be continuous, closing without any open ends, and not intersecting.

Step by step solution

01

Understand the characteristics of magnetic field lines

Magnetic field lines are a visual representation of the magnetic field surrounding a magnet. They radiate out from the north pole of the magnet and curve around to return back to the south pole. The density of the field lines at any point within the field represents the strength of the magnetic field at that point. In our case, the orientation of the magnets will cause the field lines to interact and form specific patterns.
02

Sketch the individual magnetic field lines of both the magnets

Before combining the fields, draw the magnetic field lines for the individual magnets. For each magnet, draw lines that start at the north pole, curve around, and return to the south pole. Since the north poles are at opposite ends, the field lines near each end will behave differently. At each end, the magnetic field lines will emerge from the north pole of one magnet and also extend towards the south pole of the other magnet.
03

Combine the magnetic field lines for both the magnets

Since the magnets have their north poles at opposite ends, this means that the south pole of one magnet is next to the north pole of the other. The magnetic field lines of both magnets will combine at the center, where they are next to each other. Draw field lines starting from the north pole of the first magnet, curving towards the other magnet's south pole, and then return to the first magnet's south pole (forming a loop). Similarly, draw field lines from the second magnet's north pole, curving around to the south pole of the first magnet, and return back to the second magnet's south pole.
04

Sketch the field lines at the outer sides of the magnets

At the outer ends of both bar magnets (where there are north poles at the opposite ends), the field lines will repel each other as they have the same direction, and they will form loops as they attempt to find a way back to their respective south poles, which are now further away from the north poles. Sketch these loops extending outwards from both ends of the magnets before eventually returning to their corresponding south poles.
05

Evaluate the sketch of the magnetic field lines

Make sure that the magnetic field lines are continuous, closing without any open ends, and that they don't intersect. The lines should clearly show the pattern of the repelling fields at the outer ends and the attracting fields at the center where the south pole of one magnet is close to the north pole of the other. The sketch should help in visualizing the effect of the magnets' orientation on the magnetic field around them.
