Two coplanar and concentric circular loops of wire carry currents of I1 = 6.20 A and I2 = 2.50 A in opposite directions as in the figure below. (a) If r1 = 12.0 cm and r2 = 8.60 cm, what is the magnitude of the net magnetic field at the center of the two loops? 1

Solutions

Expert Solution

B = μ/2 (i1/r1 - i2/r2) = 4*3.1416e-7/2 * (6.2/0.12 - 2.5/0.086) = 14.2 μT

into the page

6.2/0.12 = 2.5/r2

r2 = 4.84 cm
