How much current would have to flow through the wire to create a field at the loop\'s cen- ter that is twice as strong as the earth\'s magnetic field (-0.5 gauss)? Imagine winding N turns of wire in a cdrcular loop of radius R, and assume the wire is so thin that the width of a bundle of N wires is

Solution

Given Magnetic field of loop os

B=2B_earth =2*0.5 =1 gauss

1 gauss =1*10^-4 Telsa

=>B=1*10^-4 Tesla

Magnetic field at the center of the circular loop is given by

B=u_oI/2R

So current through the wire is

I=2RB/u_o =2*0.1*1*10^-4/(4pi*10^-7)

I=15.92 A
