Fuller, Robert W. (Robert Warren), 1871-1953, Brownlee, Raymond B. (Raymond Bedell), b. 1877 joint author, Carhart, Henry Smith, 1844- First principles of physics. [from old catalog] · Boston, Allyn and Bacon · leaf 320
o-pole, drum-wound small dynamo (6-8 volts); voltmeter;dry or storage cell, or other source of current for exciting thefield of the dynamo. Introductory: Voltaic cells are not adapted to produce high pressuresand large currents. Hence dynamos are employed incommercial work. Their action depends… … dynamo is called the field magnet. The conductors whichcut the lines are wires wound about a soft iron core. Thewires and core together constitute the armature. Thecurrent generated in the armature is led out into theexternal circuit by means of brushes, which make a slidingcontact with bars…
