Question

A wire in the shape of an equilateral triangle with sides of length $1.00m$ is kept in a magnetic field of $2.00T$, pointing to the right. Find out the magnitude of the magnetic flux passing through the triangle?

• A. $0Wb$
• B. $1.00Wb$
• C. $1.73Wb$
• D. $2.00Wb$
• E. $3.46Wb$

Answer 1

The correct option is A $0Wb$

Magnetic flux $\varphi =\overrightarrow{B}.\overrightarrow{A}$

From figure, the area vector of the loop is perpendicular to the magnetic field i.e $\overrightarrow{A}\perp \overrightarrow{B}$

$\therefore$ $\overrightarrow{B}.\overrightarrow{A}=0$ $⟹\varphi =0$ $Wb$
