Following our investigation into motional electromagnetic induction [J. Guala‐Valverde, Apeiron 8, 41 (2001)], we search for the torque location in “confined B‐field” homopolar dynamotors. Angular momentum conservation precludes a local interaction between the magnet creating the field and a current‐carrying wire, as happens in the “open B‐field” configurations formerly investigated. Angular momentum balance takes place now between the active current and the magnet plus the yoke as a whole.
Keywords: confined B field, torque location, angular momentum balance, rotating field lines
