8- Earth's magnetic field (013): In this experiment a student plotted a graph of tan(0) versus I (mA) as shown in the figure. The measured horizontal magnetic field of the earth is 0.3203 104 T. If the radius of the coil used is 10 cm then the number of turns N is: A. 202 B. 400 C. 298 D. 106 tan(8) 1.04 14 50 I(MA)
