QUESTION #51 Magnetic Field due to a Current Element
A regular polygon of 6 sides is formed by bending a wire of length 4pi meter. If an electric current of 4pisqrt3mathrm~A is flowing through the sides of the polygon, the magnetic field at the centre of the polygon would be x times 10^-7mathrm~T. The value of x is:
