Question

A coil of area of cross section $0.5m^2$ with $10$ turns is in a plane which is perpendicular to a uniform magnetic field of $0.2Wb/m^2$. The flux through the coil is:

• A. $100$Wb
• B. $10$Wb
• C. $1$Wb
• D. Zero

Answer 1

The correct option is C $1$Wb

The flux through a coil with n turns is given by , $\varphi =nBA$ where $B=$ magnetic field and $A=$ cross section area of coil.

So, $\varphi =10\times 0.2\times 0.5=1$ Wb
