The properties of magnetic bipoles are analyzed. For this purpose, magnetic bipoles of different sizes are identified using SDO/HMI magnetic field data for the period 2010–2024. The distribution of bipoles in the solar cycle is considered depending on the magnetic polarity in the Hale law. It is shown that magnetic bipoles of the polarity corresponding to the current 22-year magnetic cycle arise at high latitudes 2–4 years before the first sunspots appear. This distribution of magnetic bipoles is consistent with the hypothesis of the extended solar cycle. The dependence of the length of the bipole magnetic axis, , on the magnetic bipole area is analyzed. It is shown that there is a local maximum of the parameter corresponding to distances –20 and 86 Mm. The distribution of bipoles is plotted in the coordinates of tilt-angle, τ, and length of the magnetic axis, . The −τ diagram shows inhomogeneities possibly associated with the influence of supergranulation on the bipoles.
