A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder), the electrical polarity depending on the direction of rotation and th...

<physics> A direct-current generator in which the poles presented to the armature are all of the same polarity, so that the voltage generated in the active conductors has the same polarity at all times. A pure direct current is thus produced without commutation. ... (09 Oct 1997) ...
