Question

A square coil ${10}^{-2}{m}^2$ area is placed perpendicular to a uniform magnetic field of intensity ${10}^{3}Wb/m^2.$. The magnetic flux through the coil is

• A. $10$ weber
• B. ${10}^{-5}$ weber
• C. ${10}^5$ weber
• D. $100$ weber

Answer 1

Answer: (A)

$10$ weber

$A={10}^{-2}{m}^2$

$B={10}^{3}Wb/m^2.$

$\varphi =BA=10weber$
