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.

7mC

Answer Key / Explanation : (a) -

Q= = A(Bf−Bf)= 3.5 10−3

= (3.5 10−3)(0.4−0)

=1.4 10−4 = 0.14mC
