3 To measured a magnetic field between the magnetic poles of a loud speaker a small coil having 30 turns and 2 5 cm area is placed perpendicular to the field and removed immediately If the total charge flown through the coil is 75 x 10 C and the total resistance of wire and galvanometer is 0 3 2 then the magnitude of the magnetic field is a 0 03 T b 0 3 T c 3 T d 3 10 T
