Confined B-Field Homopolar Dynamotor

摘要

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.
