Magnetic Field Due to Straight Current Carrying Wire: Practice Problem & Solution

A current I flows in a thin wire, shaped as regular polygon of n sides which can be inscribed in a circle of radius R. The magnetic field induction at the centre of polygon due to one side of the polygon is :
\[tan\frac{\pi}{n} tesla\]
\[\frac{\mu_{0}I}{\pi R}\left[ tan\frac{\pi}{n} \right] tesla\]
\[\frac{\mu_{0}I}{2\pi R}\left[ tan\frac{\pi}{n} \right] tesla\]
\[\frac{\mu_{0}I}{2\pi R}\left[ cos\frac{\pi}{n} \right]\]
