A circular coil of radius 10 cm is placed in a magnetic field \(\vec{B}=(1.0 \hat{i}+0.5 \hat{j}) \mathrm{mT}\) such that the outward unit vector normal to the surface of the coil is \((0 \cdot 6 \hat{i}+0 \cdot 8 \hat{j})\) . The magnetic flux linked with the coil is:
- \(0.314 \mu \mathrm{~Wb}\)
- \(3 \cdot 14 \mu \mathrm{~Wb}\)
- \(31 \cdot 4 \mu \mathrm{~Wb}\)
- \(1.256 \mu \mathrm{~Wb}\)
Answer
(C) 31 4 ~Wb
