In a diagram where the electric field is plotted against distance, what will the graph of the magnetic field \( B \) with respect to the distance \( r \) look like?
Show Hint
The magnetic field produced by a current-carrying wire decreases with the square of the distance from the wire. In the case of solenoids, the magnetic field strength decreases with distance from the center.
Step 1: Understanding the magnetic field behavior.
In the case of a solenoid or a magnetic field around a wire, the magnetic field strength decreases with distance from the source (such as the center of the solenoid or the current-carrying wire).
Step 2: Conclusion.
The magnetic field \( B \) typically decreases as \( r \) increases, so the correct answer is (B).
