Q.1 (a) A filament loop that will carry current I is to be bent and take the form of a regular polygon with all sides having the same length. Angle from the centre of any regular polygon to one of its side is given as 2n/n as shown in Figure Q.1(a) where n is the number of sides that the polygon has. The radius of circle circumscribing the polygon is r. Using Biot – Savart's Law, determine magnetic field intensity, H at the centre of the polygon-loop to be designed with respect to n.

Transcribed Image Text:Q.1 (a) A filament loop that will carry current I is to be bent and take the form of a
regular polygon with all sides having the same length. Angle from the centre
of any regular polygon to one of its side is given as 2t/n as shown in Figure
Q.1(a) where n is the number of sides that the polygon has. The radius of
circle circumscribing the polygon is r. Using Biot - Savart's Law, determine
magnetic field intensity, H at the centre of the polygon-loop to be designed
with respect to n.
