Consider a regular polygon with $N$ sides (and therefore $N$ vertices) such that the distance between its center $O$ and each of its vertices is $r$. At each vertex of the polygon, a charge $q$ is placed (see figure 1). What is the electric field ${\bf E}$ produced by these charges at the point $O$? INTRODUCTION: I had been doing some problems on "Magnetic field due to a current." Now i have one in which one has to find the field at the centre of a regular n-sided polygon. I dont know why i'm not getting it. what will be the magnatic field at the centre of an n -sided regular polygon if centre to the vertex distance is 'a' and the current is B at center of square loop and regular polygon. Pollack and Stump, 8-11 pg. 299. Find the magnetic field at the center of a square loop of size 2a X 2a carrying current I. Repeat the calculation for a regular polygon with n sides, letting the perpendicular. find magnetic field at the center of regular polygon having n sides and edge length=l? what if n----->infinity Magnetic field at the centre of regular polygon of 'n' sides which is formed by wire, which carries current I and side of polygon is 'a Find the magnetic field at the center of a square loop of size 2a x 2a carrying current I. Repeat the calculation for a regular polygon with n sides, letting the perpendicular distance from the center to any side be a. Show that the result approaches the field at the center magnetic field at the center of hexagon ... How to find Magnetic Field at the Centre of ANY POLYGON!!! Find the field at the center of a regular n-sided polygon, carrying a steady current I. Again, let R be the distance from the center to any side. Check that your formula reduces to the field at the center of a circular loop, the limit n rightarrow infinity. Title: Comparing a current-carrying circular wire with polygons of equal perimeter; Magnetic field versus magnetic flux 5.22). Find the field at the center of a regular n-sided polygon, carrying a steady current I. Again, let R be the distance from the center to any side. Check that your formula reduces to the field at the center of a circular loop, the limit n rightarrow infinity. The direction of the magnetic field at a distance from the wire is tangential to a circle of radius ,as shown. Note that both the angles and are acute angles. where the direction of the field is given by the Right hand rule. A conductor in the shape of an n-sided polygon of side carries current . Physics equations/Magnetic field calculations. The rest of solution resembles the calculation of the magnetic field at the center of a loop. Title: Comparing a current-carrying circular wire with polygons of equal perimeter; Magnetic field versus magnetic flux Find the magnetic field at the center of a square loop of size 2a X 2a carrying current I. Repeat the calculation for a regular polygon with n sides, letting the perpendicular distance from the center to any side be a. Show that the result approaches the field at the center of a circular loop of radius a in the limit .
