Q1

A circular coil of radius 10 cm is placed in a magnetic field \(\vec{B}=(1.0\overset{^}{i}+0.5\overset{^}{j})\mathrm{mT}\) such that the outward unit vector normal to the surface of the coil is \((0\cdot 6\overset{^}{i}+0\cdot 8\overset{^}{j})\). The magnetic flux linked with the coil is :

a

\(0\cdot 314\mu \mathrm{Wb}\)

b

\(3\cdot 14\mu \mathrm{Wb}\)

c

\(31\cdot 4\mu \mathrm{Wb}\)

d

\(1\cdot 256\mu \mathrm{Wb}\)
