Following our investigation into motional electromagnetic induction [J. GualaValverde, Apeiron 8, 41 (2001)], we search for the torque location in “confined Bfield” homopolar dynamotors. Angular momentum conservation precludes a local interaction between the magnet creating the field and a currentcarrying wire, as happens in the “open Bfield” 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
