Figure 30-37a shows a circuit consisting of an ideal battery with emf # ! 6.00 mV, a resistance R, and a small wire loop of area 5.0 cm2 . For the time interval t ! 10 s to t ! 20 s, an external magnetic field is set up throughout the loop. The field is uniform, its direction is into the page in Fig. 30-37a, and the field magnitude is given by B ! at, where B is in teslas, a is a constant, and t is in seconds. Figure 30- 37b gives the current i in the circuit before, during, and after the external field is set up. The vertical axis scale is set by is ! 2.0 mA. Find the constant a in the equation for the field magnitude.
