It is well known that a relativistic rotating charged disk approximates in the limit of (v = c) the Kerr-Newman solution with (B = 0): https://arxiv.org/pdf/gr-qc/0410109.pdf. However the total field energy of such a rotating disk would be infinite, this is one of these examples in physics, where you run into pathologies. As is remarked in the paper those might be removed by a quantum treatment. For v &lt; c the field energy is…</p><p><a href="https://hackerpaper.kaipfister.de/p/gr-qc_0410109/">Paper and discussion history</a>. A mention is not an endorsement.</p>gr-qc
