I'm having trouble solving E9B.6

Esp 3 How muc hose strength is ong straight wire carries a current of 200 A. EB4 A long s EMBA What is the magnetic field strength at a pont 3m from the wire? A circular loop of wire has a radius of 12 cm and carries a current of 0.5 A. what is the magnitude of the magnetic field at its center? How does this com- pare to the magnitude of the earth's magnetic field? EsB.5 EB6 Imagine that you have a loop of wire 10 cm in di- ameter. 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

Explanation / Answer

Given Magnetic field of loop os

B=2Bearth =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=uoI/2R

So current through the wire is

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

I=15.92 A
