A simple 2-pole dc machine consists of a rotating loop inside a magnetic field B = 2 T. The radius and length of the loop are 0.2 meter and 0.4 meter, respectively. The loop is connected in series to a battery VB = 120 V and a resistor R = 0.5 N via slip rings and carbon brushes (commutator). The current of i is flowing from the battery to the loop. The power loss in the resistor R is 320 W.
