Maydon o‘zgarayotgandagi induksion tok
Figure (A) shows a circular conductor in a uniform magnetic field perpendicular to the page; figure (B) shows the field strength against time. If the induced current is I 1 for 0 < t < t 0 (interval 1) and I 2 for t 0 < t < 5t 0 (interval 2), what is I 1 : I 2?
