Unformatted text preview: 1.3. In that example, however, it was shown that we could replace the permanent magnet with an externally excited terminal pair; hence this case imposes no restriction on our development. We can also study electric field systems using the conservation of energy. For the example in Fig. 3.1.2, with the electrical energy stored in the system denoted by We, the conservation of power can be written as
dW, dq dz -=v -- dx fq -(3.1.12) dt dt dt and multiplication by dt yields the conservation of energy
