Diagram showing a segment of wire carrying electric current, with labeled axes and arrows indicating the direction and magnitude of the magnetic field at various points around the wire. The wire runs horizontally, and magnetic field vectors are shown at numbered positions, illustrating how the field varies with distance and orientation.

A line graph showing peak current in amperes on the vertical axis versus angular frequency in units of ten thousand radians per second on the horizontal axis. The curve rises sharply to a peak near 3.5 on the horizontal axis, marked with a dotted line labeled omega sub r, then falls symmetrically. The background is light blue.
