Question
A square loop of area 2.5 × 10-3m2 and having 100 turns with a total resistance of 100Ω is moved out of a uniform magnetic field of 0.40 T in 1 sec with a constant speed. Then work done, in pulling the loop is -


Options
A.zero
B.1 mJ
C.1 μJ
D.0.1 mJ
Solution
W = Fl = N(IlB) l = N
l2B = 
∵ t =
∴ W =
= 0.1 mJ
∵ t =
