Quiz os (2), 28 November 2018 Fill in the Blanks I=40 A 1 = 0.20 m Figure Q8.1 Equilateral triangular current-carrying loop A conducting loop in the shape of an equilateral triangle of edge length 0.20 m carries a currentI 4.0 A as shown in Figure Q8.1. Calculate the magnitude of the magnetic field generated by one side of the loop at the center of the loop. Unanswered

Answer 1

Length of altitude

tan 60 = L / 0.1

L = 0.1732 m

As we kniw the centroid of the traingle divides the median in (2:1) then

Distance of the cebter from lower side

d = (1/3) L = 0.058 m

Magnitude of magnetic field is given by

B = (uo/ 4 pi) 2 i / d

B = 10^-7 * 2* 4 / 0.058

B = 1.38*10^-5 T
