No, a magnetic field is not a discrete bunch of lines. The most true-to-life representation of the magnetic field is, in my opinion, the arrow diagram. The field isn't really arrows with a spatial extent, nor is it discrete like that. But the diagram gives you a sense that there is a strength and a direction at every point, and shows you the ...

The cues could be the magnetic inclination – the dip angle between Earth's magnetic field and Earth's surface – or the magnetic intensity, the overall strength of Earth's magnetic field. Earlier research suggested similar ideas as a means for birds to return to their desired flight paths if an extreme weather event had sent them off course.

Strategy Consider an arbitrary plane perpendicular to the wire, with the current directed out of the page. The possible magnetic field components in this plane, B r B r and B θ, B θ, are shown at arbitrary points on a circle of radius r centered on the wire. Since the field is cylindrically symmetric, neither B r B r nor B θ B θ varies with the position on this circle.
