Two parallel conducting rails a distance 1 apart are connected at one end by a resistance R in series with battery of emf E. A conducting bar completes the circuit, joining the two rails electrically but free to slide along them. The whole circuit is perpendicular to a uniform magnetic field B, as shown in (Figure 1). The bar is initially at rest, and nothing is pulling it.
