WebSep 12, 2024 · The magnetic field lines are shaped as shown in Figure 12.5.2. Notice that one field line follows the axis of the loop. This is the field line we just found. Also, very close to the wire, the field lines are almost circular, like the lines of a long straight wire. Figure 12.5.2: Sketch of the magnetic field lines of a circular current loop. WebFeb 20, 2024 · The magnetic field created by current following any path is the sum (or integral) of the fields due to segments along the path (magnitude and direction as for a straight wire), resulting in a general relationship between current and field known as Ampere’s law. The magnetic field strength at the center of a circular loop is given by.
