Question

A closed circuit is in the form of regular hexagon of side $a$. If the circuit carries a current $I$, what is magnetic induction at the centre of the hexagon?

• A. $\frac{\sqrt{3}{\mu }_{0}I}{4\pi a}$
• B. $\frac{\sqrt{3}{\mu }_{0}I}{2\pi a}$
• C. $\frac{\sqrt{3}{\mu }_{0}I}{3\pi a}$
• D. $\frac{\sqrt{3}{\mu }_{0}I}{\pi a}$

Answer 1

The correct option is D $\frac{\sqrt{3}{\mu }_{0}I}{\pi a}$
