A conducting circular loop made of a thill wire, has area 3.5
10−3 m2 and resistance 10Ω. It is placed perpendicular to a time dependent magnetic field B(1) = (0.4T)sin(50
t). The field is uniform in space. Then the net charge flowing through the loop during t = 0 s and t = 10 ms is close to:
|
a. |
14mC |
b. |
21mC |
|
c. |
6mC |
d. |
