- half revolution.It will help us tounderstand just whatis happening in the re-volving coil if we firstconsider what wouldhappen in a singleloop of wire which is rotated in a magnetic field (Fig. 87). Ifwe start with the plane of the loop vertical and turn the handlein a clockwise direction, the… … Fig Single loop of wire turning in a mag-netic field. ELECTROMAGNETIC INDUCTION 143 wire AD is moving up, and the current tends to flow fromA to D. The result is that during the first half turn the cur-rent goes around the loop in the direction ADCB. During thesecond half turn the current is…
